CC: Al, you're in the mud. You'11 have to try me on that one again.
CMP: Okay. Just wanted to let you know that I've also got the rendezvous transponder on.
CC: 0keydoke. Thank you Al.
CC: Endeavour, Houston. One minute to T-1.
CC: Thirty seconds to T-2.
CC: Ten seconds to T-2, Endeavour.
CMP: Okay, Houston; Endeavour. Through with tracking, but I'm not sure they're very good marks.
CC: Okay, Al; we understand. High Sun angle may have made it difficult.
CMP: Yes, I seemed to have a lot of interference and sextant, from the landmark, by the sight - part of the optics.
CC: Al, do you think you saw him at all?
CMP: Yes. I think the first couple of marks were on him, Ed, but I couldn't hold him.
CMP: I kept - I kept losing him.
CC: Endeavour, Houston. In the blind, give us the best OMNI, please.
CC: En - Endeavour, Houston. Best OMNI, please.

CC: Endeavour, Houston. In the blind. How do you read?
CC: Endeavour, Houston. Give us your best OMNI, please.
CC: Endeavour, Houston. In the blind. I'm going to give you a lift-off time: 171:37:22.36. We'11 uplink you at AOS since we have no contact. And, Endeavour; Houston. TPI, 172:29:39.00. I'11 re- peat, lift-off, 171:37:22.36; TPI 172:29:39.00. CSM weight for your DAP 35995.
CC: And, Al, if you read. Let's come around to AO$. Trying to get comm. We'11 have a lot of work to do.
CC: Endeavour, Houston. One minute to LOS.
CMP: Roger, Houston; Endeavour. And did you get the gyro torquing angles, Ed?
CC: Al, we haven't had you for the last 20 minutes. Did you get my uplinks - or rather my pads up?
CC: Okay. Let me give you one quickly, you've got 40 seconds to LOS. T. is 171:37:22.36. TPI, lg 172:29:39.00. Your CSM weight 35995. I'm going to lose you in about 15 seconds. We'11 get all your uplinks and the rest of the pads at AOS. Tape lll/1 APOLLO 15 AIR-TO-GROUND VOICE TRANSCRIPTION
CC: 2, all zeros. We copy 47053.
CDR-LM: ... ASCENT BATS, OFF.
UNKNOWN: Roger. ASCENT BATS going On now, Ed.
CC: And, Falcon, we will not uplink you at lift-off minus 35. You can press on with your checklist.
CC: Okay, Al. Loud and clear.
CMP: Okay, Ed. I'm in REACQ NOUN now.
CC: Roger. And, Falcon, your 047053 are okay. Al, did you get the TPI and lift-off time for the direct ascent before LOS? Over.
CC: Okay. Let us have POO and ACCEPT, and we'11 give you an uplink.
CMP: You have it.
CC: Okay. Let me give you the coelliptic pad, Al.
CMP: Go ahead. CSI, 172:35:08.00, and NOUN 37, your T. TPI is lg 174:27, all zeros. Read back.
CMP: Okay. I understand on a direct it's lift- ascent, off, 171:37:22.36; TPI, 172:29:39.00; CSM weight, 35 995; coelliptic lift-off, 171:40:13.41; CSI, 172:35:08.00; TPI, 174:27:00.00
CC: Okay, Al. That's a good readback. And, Al, let me advise you that be - because of your orbit, the TPI is going to be nonnomlnal in angle, about the - about the same DELTA-V; however, a different angle. We'11 have more words after insertion. 4
CMP: Okay. Do you want the gyro-torquing angles on that last P527
CC: That's affirmative. I'm ready to copy.
UNKNOWN: Okay. Minus 4 balls 6, minus 00017, and minus 00017, and they were torqued out at 17006.
CC: Copy minus 4 balls 6, minus 3 balls 17, minus 3 balls 17, torqued at 17006.
CC: And give us AUTO on the HIGH GAIN. And, Al, we're not going to bother with your - P27 pad readup, unless you're especially wanting it.
CMP: Negative, Ed.
UNKNOWN: And, Endeavour; Falcon. You're five square to us on the relay. How do we sound?
CMP: Hello, Falcon; Endeavour. You're loud and clear.
UNKNOWN: Okay. We're all set. Ready to - get us some warm chow?
CDR: Great. I'11 tell you, cold tomato soup isn't too good.
CC: Endeavour, the computer is yours.
CC: Al, were you having any corem difficulties before LOS on the - our last pass. We lost you for about 20 to 25 minutes.
CMP: Sure didn't notice any, Ed. I was busy down in the LEB, but I didn't get any - any signal in the head- set indicating that we'd lost S-band lock, and I had the SQUELCH OFF.
CC: And, Falcon; Houston. I have some PIPA biases, when you'd like them.
CDR-LM: Stand by, Ed.
CC: Falcon, Houston. Verify SLEW. We're about to hand over.
LMP-LM: We're going SLEW. please.
LMP-LM: Roger. Going back to AUTO.
CC: And, Falcons Houston. I still have some PIPA biases I need to give you.
CC: Okay. Falcon, Houston. Observe you're into VERB 83 at lift-off minus 12. We're right on schedule. I have a couple of updates for you, please.
CC: Falcon, Houston. Do you read?
CC: Falcon, Houston. In the blind while we're looking at our corem problem. Your PIPA bias: VERB 21 NOUN 01 ENTER. ENTER it - put that in if you hear me.
CC: Okay, Falcon. There we have you. We had a little net problem. I have a PIPA bias update for you.
CDR-LM: Well, stand by. You ready to watch the APB pressurize?
CC: Okay, let's let her go.
CDR: Okay, here comes tank 1. And we'11 stand by for your call for tank 2.
CC: Okay. Go with tank 2, looks good.
UNKNOWN: Okay. Tank 2 coming now.
CC: Looks good down here.
CDR-LM: Okay, thank you. Looks good up here.
CC: And, Dave, you're GO for the direct rendezvous. Both guidance systems look good; PGNS is your recommendation.
CDR-LM: Roger. Go for direct on the PGNS.
CC: Falcon, are you still with us?
CC: Okay. Have a couple of n_mhers I need to read for you, Dave, when you're ready.
CDR-LM: Okay. Pencil's out. Go ahead.
CC: Okay. PIPA bias is Y PIPA: VERB 21 NOUN 01, 1454 ENTER; and the data is 04366 ENTER. X PIPA: VERB 21 NOUN 01; address, 1452 ENTER; data 04672 ENT_R.
UNKNOWN: Okay. Here's the readback on that Ed. VERB 21 NOUN 01; 1454 ENTER; 04366. And, then ¥_B 21 NOUN 01; 1452 ENTER; 04672.
CC: That's a good readback. And when you have your Timeline Book out, I'd like to change some range and because range rate n,,mbers of this ellipticity of the command module orbit.
CDR-LM: Okay, Ed. Do you want those PIPA biases loaded now?
CDR-LM: Oka_r, Ed. What are the changes in the Timeline Book?
CC: Okay. The range and range rate at insertion: range rate is 137; range, minus - sorry, the range is 137; range rate, minus 431; at plus 5 minutes, range 117; range rate minus 398; and at 10 minutes, range is 98, range rate minus 355.
CDR-LM: Okay, I copied that data.
CDR: Falcon, Endeavour, on VHF. How do you read?
CDR-LM: Okay, Falcon; Endeavour. How do you read us now? 5 by?
CC: And, Falcon; Houston. We'd like you to change your 053 m_mber to plus 01722.
LMP-LM: Copy. The 053 to plus 01722.
CDR-LM: Roger. W e tried, and I got no response, and I'11 stand by. We should be hot miked to the Endeavour.
CDR-LM: Okay, Houston. We've got trouble on the VHF check - as he approaches the mountains back there - we usually don't get him until he's almost overhead, because of the interference.
CMP: Okay, Falcon, there you are. I've got you now.
CDR-LM: Oh, okay.
CC: Understand VHF check is good now. - -
CMP: Reading you 5 square on VHF there, Dave.
CDR-LM: Roger. VHF cheek is GO, Ed. Falcon here.
CC: Endeavour, Houston. We're going to hand you over no_g.
CDR-LM: VOX - Hey, Houston, Falcon. How do you read on VOX?
CC: Okay, loud and clear, Dave, and you're GO for lift- off. And I assume you've taken your explorer hats off, and put on your pilot hats.
CDR-LM: Yes sir, we sure have. We're ready to do some flying.
UNKNOWN: Standing by for i minute.
LMP-LM: Guidance steering is in.
CC: Mark. One minute.
CDR-LM: Okay, MA - - MASTER ARM is ON; I have 2 lights.
UNKNOWN: Average g is on.
CDR-LM: ABORT STAGE; ENGINE ARM to ASCENT. 99 PRO.
UNKNOWN: Good lift-off. Automatic. Yaw left. Pitch over.
CDR-LM: Phasing, about 306.
CDR-LM: Hey, good smooth ride, Ed.
CC: Roger. Copy now.
CDR-LM: All looks good at 30.
CC: Falcon you're GO at - -
CC: - - 1 minute. AUTO start; normal shutdown.
CDR: Roger. AUTO start and norm, 1 shutdown.
CC: Both guidance systems are good, Dave.
CDR-LM: Okay, looks good up here. It almost sounds like the wind whistling, doesn't it.
LMP-LM: Boy, what a view of the rille, huh? Bolder tracks slip down into_ it. (Music - "Air Force Song,)
CDR-LM: ... on the ...
CDR-LM: ... right on profile.
CC: Falcon, Houston. You're looking good at 3 minutes.
UNKNOWN: Roger. The only thing unusual I noticed is the RCS OXIDIZER manifold pressure oscillates every time the Jets fire. That's backing up to the ...
CC: Falcon, Houston. You're GO at 4.
UNKNOWN: ... radar lockup.
LMP-LM: 5 minutes ....
CC: Falcon, Houston. You're still looking good. Your PGNS is showing a slight radial error, but it's a little bit lower than nominal. But everything's GO.
CDR-LM: Roger. Understand.
CDR: ... rendezvous radar ...
LMP-LM: ... a thousand to go .... 500.
CC: Falcon, Houston. Trim AGS.
CDR-LM: Roger. Understand. Trim the AGS .... connection?
CC: Falcon, Houston. Trim in plane only.
CDR-LM: Roger, in plane only on the AGS ....
CDR-LM: *#* ARM is OFF. Okay. We'11 shut down on the PGNS. Okay, AUTO shut down .... AGS 500.
CDR-LM: 502 ....
LMP-LM: AGS MASTER ALARM.
LMP: Hey, we got a MASTER ALARM on the AGS, but we trimmed the AGS.
CC: Okay, is your - -
CDR-LM: Stand by for a tweak or a trim.
LMP: That's the self test. Okay.
CDR-LM: PGNS says its in a 40.6 by 8.9.
CC: Roger, we copy. Guidance still looks good to us.
CC: Falcon, your AGS still looks good.
LMP-LM: Okay, we copy.
CDR-LM: Okay, Understand. AGS still looks good.
CC: Falcon, Houston. No tweak.
CDR-LM: Roger, no tweak. Thank you.
CMP: Okay, Falcon; Endeavour. I got you locked up on the VHF at 127.
CDR-LM: Okay, I understand. 127, Al. You reading? lll/9 Tape
CDR: Okay, we're pitching up the radar track attitude. We didn't get a lock on it on the way up. We'11 give you a call as soon as we get locked up.
CMP: Okay. I was watching for that and I'11 let you know.
CDR-LM: And, Houston, we're watching the roll angle.
CC: Falcon, Houston. We have you at a 42 by 9. You're looking good.
CDR-LM: Okay. 42 by 9.
CDR-LM: ... , Jim?
CMP: There, you're locked on now.
CDR-LM: Roger. We're locking up now.
CMP: Roger. Got good signal strength on you.
CMP: VHF range has us at ll7 now. ll7.
CC: Endeavour, Houston. We're ready to uplink you.
CMP: What kind of range is radar giving you, Dave?
CC: And, Falcon; Houston. We will not up-link a state vector to you, your PGNCS and AGS are both good. And we will keep them independent.
CDR-LM: Falcon, Roger.
CC: Endeavour, Houston; the computer's yours.
CC: Okay, Falcon; Houston. I have a MBFN TPI for you and some words.
UNKNOWN: Go ahead. I'm ready to copy the TPI, Ed.
CC: Okay, it's an off-nominal TPI and angle. DELTA-V X, 66.3; DELTA-V Y, plus 7.8; DELTA-V Z, minus 31.2; total 73.7. TPF DELTA-V will be 26.0. You're going to be pointed _lmost along the line of sight for TPI. You can omit the roll maneuver for TPI, your choice. And you will undoubtedly break lock.
UNKNOWN: Okay, on the pad I have plus 66.3, plus 7.8, minus 31.2; and total for 73.7, and 26.0 for TPF.
CC: That's affirm. And the approach at TPF is going to be right along the local horizontal.
CDR: Okay, thanks for the information, Houston. I think if radar's working good, and we get a good solution, we will probably stay heads up and go ahead and accept the breaklock.
CC: Roger. Roger. And, Endeavour; Houston. The same goes for you. Your attitude, if you were to have to make the burn would be along the line of sight as well.
CDR: And, Houston; Falcon. I have a visual on the Endeavour now. And the COAS is exactly boresighted; the radar needles are boresighted, and the PNGS needles are boresighted, and the AGS needles are boresighted, so we're looking pretty good.
CC: And, Falcon; Houston. As far as we can tell, your AGS is completely GO. We see no reason for the master alarm yet.
UNKNOWN: Okay, Endeavour; Falcon. I'm looking at about 94 miles 355 feet per second.
CMP: Oh, Roger. I'm looking at 94 miles also.
CDR: Okay, good show. And the PNGS state vector agrees with that. lll/11 Tape
CC: And, Falcon; Houston. You're GO for an APS TPI. You have 180 feet available.
CDR-LM: Oh, Roger. Understand. GO for the APS TPI, thank yOU.
CC: Be advised your direct rendezvous TPI charts are NO GO because of this elliptical rendezvous. Your midcourse charts are good.
CDR: Okay. Understand. The TPI charts are NO GO, and the midcourse charts are good.
CDR-LM: Roger. Tracking light's on.
CDR-LM: I don't see your tracking lights.
CDR-LM: Falcon, Endeavour. I don't have your lights.
CDR-LM: Houston, Falcon. What's your LOS time?
CC: Falcon, Houston LOS in 12 minutes.
CDR-LM: Roger; 12 minutes. Okay.
CMP: Yes. I got your lights now, Dave.
CMP: Okay, Falcon; Endeavour. I'm getting some large updates on you there, Dave, on the first mark.
CDR-LM: That's right. Yes, that's right. VHF's going okay. First optics is - is off. I bypassed two of them. I'11 take the third.
CC: Roger, we need to tweak up your PIPAs a little bit more, Dave, before TPI.
CDR-LM: Okay, fine. Pencil's out; go ahead.
CC: Address 1452, 05210; address 1456, 03170. And those are both VERB 21 NOUN 01.
CDR-LM: Okay, we copy. A VERB 21 NOUN 01; 1452 should be 05210, and 1456 should be 03170.
CMP: Okay, Dave. The first update was the only large one. The rest of Shem are all falling in.
CDR-LM: Okay, very good. _
CDR-LM: Okay, Houston, Falcon. We're seeing a fairly large difference in Z between the onboard solutions and the ground solutions. But, I guess that can be expected at the recycle.
CC: I'm checking it for you now, Dave. Your PGNS and AGS seem to agree pretty well.
CDR-LM: Roger. And I think we can expect a fairly large Z at the recycle.
CC: I'11 give back some words on the MSFN TPI in a minut e.
CC: Falcon, Houston. We're going to watch it for a few more minutes and see how they converge with the other solution.
CMP: Okay, Dave. I've got a recycle solution for you. Roger. Minus 69.4, minus 6.2, plus 12.0.
CC: Endeavour, Houston. I need OMNI Alfa.
CMP: OMNI Alfa. Houston, Falcon.
CC: Roger, FIDO thinks you had a good solution, but not a great solution before. He's now saying the Z component will be - should converge to about a minus 19. And if it does, your approach angle with be more nominal - rather than along the horizont al.
CDR-LM: Okay, that sounds like we're all converging to the same spot. Thank you.
UNKNOWN: Okay, Houston; Falcon. Our polar plot is showing probably us pretty nominal. I guess we'11 stay with the nominal procedures on the TPI.
CC: Roger, Falcon. We have you a minute to LOS. Your solutions look good in both computers. We'11 see _ou on the other side. And be advised: we did _tto_our ii_ff, 6n_ _ Can confirm you l_fted off.
CDR-LM: Well, very good. That's nice to know, thank you much. Save the tapes for us, will you.
CDR-LM: Save the TV tapes for us, will you please.
CC: Ro_ger, Roger, Dave.
CC: And, Endeavour; Houston. I have you 30 seconds from LOS.
CMP: Endeavour, Roger. See you on the other side.
CC: Okeydoke, Al. Tape ll2/1
CDR-LM: Roger, Houston. Falcon had a good TPI; it burned a small midcourse l, and a small midcourse 2. Presently, we have a visual on the command module and all the solutions have been agreeing very well.
CC: Okay. Did you write down your solutions, Dave?
CDR-LM: Yes, we got them all in.
CC: Okay. We'11 ask you for them later.
CC: Hello, Endeavour. Standing by.
CMP: Okay, TV's up to ...
CC: Roger, copy. TV's on.
CC: Endeavour, Houston. We're not tracking your high gain, yet.
CC: We have your picture, Endeavour.
CMP-LM: Okay, I've got you visually there, Falcon.
CMP-LM: Yes. You're looking good.
CMP: You're very garbled, Dave. Say again.
CDR-LM: Okay, I got you at 1.28 mile.
CMP: Okay, we're right with you.
CC: Endeavour, Houston. Give us AUTO on the HIGH GAIN, please.
CMP: On AUTO.
UNKNOWN: Okay, i mile and 27 feet per second on the radar.
CC: Endeavour, Houston. Do you have the Falcon on your monitor?
CMP: No, I wasn't watching it, Ed. Stand by 1.
LMP-LM: Okay, 3000 feet, braking down to 20.
CC: Don't waste any time on it, Al.
LMP: Okay, 1500 feet, braking down to 10.
LMP: Okay, 500, braking to 5.
CDR: ... Falcon ...
CDR-LM: Okay, Houston. We're station"keeping at about 120 feet or so.
CC: Roger. Dave, during the command module pitch- around, we'd like for you to take a look at the V over H sensor in the SIM bay, if you can. Do you know how to spot it?
CDR-LM: The which sensor?
CC: V over H.
UNKNOWN: Yes, it's - it's on the pan camera gadget.
CDR-LM: Okay, I guess we're not - Well, Al's talking to US.
CC: Okay, what we're looking for is to see if any- thing is in the way of the lens of that sensor. 112/3 Tape If you're not f_iliar, I can give you a page number in your LM Data Systems Book. Just take a look at it.
CDR-LM: Okay, stand by 1.
CMP: No, it's not - it's not on the lens, Dave. It's right alongside the lens on the body of the cam- era - -
CC: We've got a picture of it, Al.
CMP: - - it tells us what speed to take the pictures at.
CDR-LM: Okay, we'11 get a picture of it.
CMP: Okay. I'11 go ahead and do your piteharound.
CMP: And, Dave, give me - give me a call when you start.
CDR-LM: Houston, what page is that on in the LM Systems Book?
CC: Okay. It's pa_e 43 in the LM Systems Bo - Data Book.
CC: Okay. On the right-hand side, Dave, you see that one little line that says, "Mapping and pan cameras N2 PRESS systems assembly."
CMP: Yes, I'11 go the higher rate, Dave.
CDR-LM: Hey, it looks good, you're going the right way.
CC: Dave, while he's pitching, I'11 tell you - should be about the middle of the SIM bay by the Mapping Camera.
CDR-LM: Very nice maneuver, Endeavour.
CDR-LM: Okay, Houston. We don't see it labeled in here. Where - Is it labeled on the picture?
CDR-LM: Okay, we got the picture; tell us where to look.
CC: Okay, way over on the right-hand side, where it says, "Mapping and pan cameras N2 PRESS system assembly."
CC: It's on the right picture.
CDR-LM: The one with the covers open?
CC: That's affirm. Between the end of that arrow and the lens, about halfway, is a little dot that represents the V over H assembly. Now, the camera lens will be covered - rather it will be folded up so you will not be able to see it; however, that is the item you are looking for, represented by the small circle about halfway in between the end of the arrow and the lens of the camera.
CDR-LM: Okay, I see a small circular object there Just - Just to the right of the handle, and I don't see anything covering it.
CC: Are you talking about the diagram or in the SIM bay.
CDR-LM: No, in the SIM bay.
CDR-LM: Yes, it's a little round, black - - 112/5 Tape
CC: That's it - that's it.
CDR-LM: - - ... type of affair, right?
CC: If you can snap a picture of it, we'd appreciate it.
CDR-LM: Okay, we'11 get one, Ed. Stand by.
CDR-LM: Okay, we've got the picture, Houston, and we'11 proceed on with the docking.
CMP: Okay, I'11 pitch back around now, Davy.
CC: And, Falcon; Houston. Do you have any comments on the SIM bay, anything look out of the ordinary?
CDR-LM: No, it looks very clean. The doors are all covered, and all the booms are retracted; and it looks neat and tidy.
CMP: Okay, where'd you go ?
UNKNOWN: We should be right where we were. Have you com- pleted your _ueuver?
CDR: Okay, we're in the same inertial attitude, I'11 come back around to you ....
CDR-LM: Okay, Endeavour. Would you handle stationkeeping, we're going to pitch and yaw now.
CDR-LM: Pitching down.
CDR-LM: Okay .... Endeavour, it's all yours.
CMP: Okay, Houston. Ready to get ... ARM, ON.
CMP: Roger. I'11 ... turn on the LOGIC when you're re ady.
CC: Okay, bring it on.
CMP: LOGIC i - LOGIC 2.
CC: Go for PYRO ARM.
CMP: ... barber pole.
CMP: Okay. You ready to come in?
CDR-LM: All set.
CDR-LM: Hard dock.
CC: Roger. Roger. Copy hard dock. And, Falcon, if you'11 give us 105 and 67, we should have your steerable .
CC: Roger. 105 and 67.
UNKNOWN: Good show, Endeavour. It's nice to be aboard again.
CMP: Welcome home.
CC: And Falcon, Houston. Now that we have the steer- able back, when you get a moment, pull the ECS AUTO TRANSFER, open, and then the GLYCOL PUMP 1 open.
CDR: Roger. ECS AUTO TRANSFER is open - and I'11 open the GLYCOL PUMP 1 now.
CC: Roger. We want to get a little data down here.
CDR: Okay, do you want us to select 2, or Just let it run?
CC: Negative. Just wait for 30 seconds.
CDR: Okay, we'11 stand by for your call.
LMP: And, Houston; Falcon. Do you have an update for us for the LM weight/CSM weight?
CC: Roger. Stand by. LM weight, 5444.
LMP: Roger. LM weight 5444.
CC: And I don't have a CSM weight at the moment. And you can close the GLYCOL PUMP i first and then the AUTO TRANSFER.
CDR: Roger. Closing GLYCOL PUMP 1 now - AUTO TRANSFER now.
CC: Roger, and I thank you.
CMP: Go ahead. All right, I got it.
CC: And, Endeavour; Houston. A couple of changes to the command module - I_4/command module transfer list on stowage items, when you get a break.
CMP: Okay, Houston. Stand by 1.
CMP: Okay, Houston; Endeavour. You might as well give me those updates now.
CC: Okeydoke, Endeavour. On page 2 - 283 -
CMP: Okay, go. z
CC: Okay, Al. About the middle of the I_Mto command module transfer list, the second DECOM bag and the fourth DECOM bag - scratch.
CMP: Understand. Scratch second and fourth DECOM bags.
CMP: Understand. Add "Collection bag (3) in A-9."
CC: Roger. And they're going to give you a - a sec- tion of core stem, three sections long, you'11 have to put that on the left-hand tray along A-1 and A-2, and secure it with - with either you I_ tiedown rope or your extra webbing in there.
CMP: Roger. I understand. The core tubes go along A-l, A-2, tied down on the tray.
CC: That's affirm. You got it.
CMP: Dave, you want to verify that the dump valve's in AUTO?
CC: Roger. Standby 1.
CMP: Okay, I'11 go ahead and start equalizing the pres- sure.
CC: And, Falcon; Flight - or rather, Falcon, Houston. FIDO's on pins and needles for your TPI solution if you can get a moment to read it to us.
CDR: Roger, we'11 do it right now.
CDR: Okay, Houston. I assume that you got the recycle before we went around the corner there.
CDR: Okay, on the final comp, I'11 read PGNS, AGS and CMC, if you are ready to copy them, in that order, in local-vertical coordinates.
CC: Roger. Ready.
CDR: Okay_ For the PGNS: plus 70.3, plus 5.9, minus 17.7. For the AGS: "pius 70.4, plus 5.9, minus 19.1. The CMC: minus 69.1, minus 6.1, plus 16.1. We burned the PGNS on time, and we had about a 4- foot-per-second overburn on the APS, which we trimmed out to 2/10ths.
CDR: Okay, the residuals were - for the PGNS after the trim - were plus .2, plus .2, and minus .4.
CC: Copy. And assume midcourses were ...
CDR: Roger. We'11 give you those, too.
CDR: Okay, and I'11 give you the same answers for mid- course 1 if you're ready to copy, Houston.
CDR: Okay, PGNS was minus 1.1, O, and minus 1.1. AGS was minus 1.5, O, and minus B.0. CS - csM, plus 1.5, minus .2, plus 1.9. And we burned the PGNS solution to O.1 and .2.
CC: Thank you, Dave, that's fine. Appreciate it.
CDR: Okay, you want midcourse 2?
CC: No, we'11 take you PGNS - we'11 take all the rest of them; we'11 get them later.
CDR: Okay, fine. It was pretty smooth all the way, every thing looked nice, and the data went in very well, and I thought it was a super rendezvous.
CC: Very good. Getting home's the main thing.
CDR: Yes, but you know, these systems are Just magnifi- cent.
CC: Yes, they sure are, Dave. Okay, we suggest you press right along With your transfer and cleaning up.
CDR: Roger. We're in work right now.
CC: And whenever Jim's ready to do the targeting, we'11 read him a pad on that.
CDR: Okay, stand by, we'11 give you a call.
CDR: Okay, Ed. I'm ready to copy the impact pad.
CC: Okay, understand you're ready for the LM impact pad, Jim; is that correct?
CC: Yes, if that's what you have to pass.
CC: Okay, it's a P30 pad. 179:06:22.50_ NOUN 81, minus 0121.9, plus 0056.0, plus 0148.8; O071.1 minus 0037.1, 0200.3; 1:27; 047, 174. The rest is NA. And the LM weight is 5444.
LMP: Roger. Readback for P30 pad. 179:06:22.50; minus 0121.9, plus 0056.0, plus 0148.8; O071.1, minus 0200.3; 174. 0037.1, 1:27; 47, And LM weight is 5444.
CC: Good readback, Jim.
CC: And, Falcon; Houston. The computer's yours.
CC: And we want to leave it in DATA, of course.
CDR: Okay, we'11 leave it in DATA. It's all yours now.
CC: And, Endeavour; Houston. Before you get LOS and get too busy with transfer, I need to give you a camera photo pad for the next pass.
CMP: Okay. Go ahead, Houston.
CC: Okay, this is the one on that 174:50, Al. T-start - for the map camera - T-start, 174:50:04; T-stop, 175:49:36. Your IMAGE MOTION BP plus 4 at T-start, and BP at 175:30:00. And your pan camera photo pad, to be copied at 175:20. T-start, 175:34:32; T-stop is 36:52. Tape ll2/11
CMP: Roger, Ed. Understand mapping camera photo pad is T-start, 174:50:04; T, stop, 175:49:26. And at T- start, you want IMAGE MOTION to go barber pole plus 4.
CC: That's affirm. IMAGE
CMP: And, at 175:30, understand you want MOTION to go to barber pole.
CC: That's affirm, Al. And the correct time for the T-stop on that was 175:49:36.
CMP: Understand, 49:36.
CMP: And the pan camera photo pad is T-start, 175:35:42; T-stop, 175:36:52.
CC: Roger. The T-start, 175:34:32; T-stop is good.
CMP: Understand, T-start is 175:34:32.
CC: That's a good readback now, Al.
CMP: Yes, it's, pressurized, Jim. Can you read me? Okay, tunnel's pressurized and I'm up in it now, checking the latching.
CDR: Hello, Houston. The Falcon is .back on its roost and going to sleep.
CDR: She's all yours now, Ed. We're going to go off corem and put her to bed.
CC: Okay, one item, Dave. You're not marking these bags before you hand them to Al, are you?
CDR: The bags are all numbered. We've got the collec- tion bags in the cover bags with the proper numbers on them, and that was all we were planning to do.
CC: Okay, you're not helping him with the stowage when you pass them in, are you? I would change your Flight Plan if you did; otherwise, I'11 Just give it to him.
CDR: Well, I guess the best thing would be to go ahead and give it to him, because we'11 Just pass them over then.
CC: Okay, I've given them to him already. Thank you.
CDR: Yes, that fine, he - he's got a much better handle on the stowage over there anyway than we do.
CC: Al, we observed when you were in P79, Just before the docking, that you got a P00 D00. Do you have any words on that?
CMP: No, I don't, Ed.
CC: And, Endeavour; Houston. We're going to have to update your Flight Plan with a couple of items before you go around the corner, whenever you can get around to it.
CMP: Okay, Ed, let's go ahead and do them now.
CC: Roger. And, Al, give us a VERB 74 while I'm' talking to you.
CMP: Roger. VERB 74.
CC: Okay, the first Flight Plan update is the - at 174:12.
CC: Okay, where it says the "Mapping camera laser ex- periment covers, open," et cetera, et cetera - de- lete that.
CC: And the second line after that, the '_ap camera trackj" et cetera, et cetera; delete that, we're going to move those to 174:40.
CMP: Okay, understand.
CC: okay, down a little bit in the next group of words where it says "Laser altimeter, on" at 174:17, we're going to scratch that.
CMP: Okay, scratch laser altimeter.
CC: We're going to move that to 174:49.
CMP: Roger. Move to 174:49.
CC: Okay, and at 175:49, going to add a - another LASER ALTIME'i'_, OFF.
UNKNOWN: Roger, understand. At 175:49, LASER ALTIMETERS, OFF.
CC: Okay, the next item is at i - Stand by on that a minute. And at 175: 54, delete the LASER ALTIMETER, OFF.
CMP: Understand. At 175:58 [sic], delete LASER ALTIMETER, OFF.
CC: And at 176:02, the next page right after all those words, we want to add in the "Map camera" - that's about 176:02 - "MAP CAMERA/LASER EXPERIMENT COVERS, CLOSE, talkback's barber pole, flash gray, then OFF." down
CC: LOOKS like that item came there about 4 min- utes later, Al.
CMP: Roger that, I see it now.
CC: Yes, I Just now saw it, too. I presume they want it moved up there a few minutes. And at 178:02; Oh, sorry about that - at 177:56, put in a "LOGIC POW_ (2), OFF. '
CMP: Okay, I understand LOGIC POWER, both of them, OFF, at 177:56.
CC: Roger. Next page, 178:02, "LASER ALTIMETER, ON," delete.
CMP: Delete "LASER ALTIMETER, ON," at 178:02.
CC: Okay. And at 179:40, following page, delete "LASER ALTIMETER, OFF" - and about 179:41, delete those two lines, "MAP CAMERA/LASER EXPERIMENT COVERS" and "LOGIC POWER (2), OFF." Delete those. Tape ll3/1
CMP: Okay. Delete th e three lines at 179:40, "LASER ALTIMETER," "MAPPING CAMERA COVERS," and "LOGIC POWER, OFF." Delete those three lines.
CC: Okay. I think we got them all that time, Al. Thank you.
CC: And, Endeavour, Houston. If you can holler at Dave and Jim, remind them that - to get their radiation meters out of their pockets. We'd still like those readings we didn't get earlier.
CMP: Roger, Houston. the HIGH GAIN? And request Falcon to go to AFT OMNI as he goes over the hill or after he's over the hill.
CMP: Okay. You want Falcon to go A_T O_I.
CC: Yes, at LOS. And you're about 3 and a half min- utes from LOS now.
CMP: Okay, I'm in AUTO and they're going to go to AFT OMNI at LOS.
CC: That's firm. And ask them when they do that to verify TRACK MODE, SLEW.
CC: And, Endeavour, we're about 40 seconds from LOS; see you on the other side.
CMP: Okay, Ed. Thanks much.
CMP: Houston, 15. Still in the midst of doing a little house cleaning.
CC: Okay; kind of figured that, Al.
CC: Endeavour, Houston. Would you ask Falcon to switch to FORWARD OMNI?
CC: And, Al, do you want to verify - verify that you got your mapping camera started at 174:507
CMP: Yes. Roger, Ed. Was i minute late on that - on the mapping camera, but we got it started at i - at 174:51.
CMP: Roger, Ed. One other thing, I didn't get the P52 put in.
CC: Okay, I understand, no P52.
CC: Al, I'11 keep track of your cameras for you and give you a warning on the stops and starts.
CMP: Okay; if you would, that would help.
CC: 15, Houston. Give me -I_ACQ and NARROW, please.
CMP: Okay,-REAcQ and NARROW.
CC: 15, Hous{on. We're having a 10t of trouble with the I_ COMM. Apparently, we're right in - in the midst of the OMNI. Let's try AFT again, please. again.
CMP: Houston, I was talking with Dave. Say
CC: again,
UNKNOWN: Let's try the IA_ A_T OMI please.
CC: 15, HouSton.
CMP: Roger, Houston. Go ahead. GA/_4A
CC: How about the RAY GAIN switch? Snap it three times for us, please, Al.
CMP: Okay, three times.
CC: Al, we're going to change your mapping camera procedures. I'm going to call them to you on time rather than read them to you now. So press on, and I'11 give you a warning here in about 5 or 6 minutes.
CMP: Yes, that'd be fine, Ed. Just give me a couple minute warnings, so I can get over to the camera. As you probably know, the LEB TIMER's not work- ing.
CC: Roger. I'11 keep you posted on time; press on.
CC: Al, we observe that your - got POO up instead of P20. Better check your attitude and get her back in P20, and let's see if our camera is pointed at anything.
CMP: Roger. That Just happened about 15 seconds ago. You must have caught it Just as it went to P00. And I don't think we're even out of the dead - band.
CC: Very good. And, Al - yes, stand by. We still got a couple of minutes yet. What I'm going to do is have you RETRACT the MAPPING CAMERA with it still running and then turn it off. We're running a little test on it. And I'11 call back for you in a couple of minutes.
CC: Apollo 15, Houston. Stand by to RETRACT the MAPPING CAMERA.
CMP: Okay, standing by.
CC: MARK. Start retracting.
CMP: Okay; it's retracting now.

CC: Okay, Al, that completes all that for us. Thank you.
CMP: Okay, Ed. Thank you very much.
CC: Okay, Apollo 15; Houston. We're getting a little itchy for some LM data. We'd like for them to bring ul_ the steerable if they can, please, at 146 and 29.
CMP: Okay, Ed. Have them bring up the steerable.
CC: Roger. Angles 146 and plus 29.
CMP: Understand. Angles 1_6 and plus 29.
CC: And, 15, we verify that your PAN CAMERA is in, and you can turn the POWER, OFF, on it.
CMP: Okay. __ _END OF TAPE
CC: Apollo 15, Houston. You can start your maneuver to Jettison attitude at any time. And I have a slight update to the attitude.
CMP: Okay, Houston, 15. Standby 1.
CC: Apollo 15, Houston. Your GAMMA RAY, GAINSTEP, SHIELD, OFF, please.
CMP: Okay, Ed. GAMMA RAY, GAIN, SHIELD going OFF.
CMP: Okay, Ed, it looks like the chaos is slowing down a little bit here, if you want to talk about the Flight Plan.
CC: Okay, Al. You can start your maneuvering to your date the attitude for you. It's ROLL 14, PITCH 38, and YAW 344.
CMP: Roger. And understand the LM Jettison attitude is ROLL 014, PITCH 038, and YAW 344.
CC: Roger. And the time is 177:20:33.
CMP: Understaad. Jettiso n time is 177:20:33.00.
CC: That's right; and the CSM SEP time here is 177:25:33.
CMP: Understand. The CSM SEP is 177:25:33.
CC: Roger. And your CSM weight for your DAP is 36,370.
CMP: Understand. DAP weight is 36,370.
CC: Roger. And I'11 call this GAMMA RAY, GAINSTEP, SHIELD, back on, Al. We want to let it go for 10 minutes yet.
CMP: Okay, GAINSTEP comes back to SHIELD, on.
CC: Negative, negative. I'11 call it back on in 10 minutes.
CMP: Roger. Roger. Understand.
CC: Roger. Would you ask Dave and Jim to make sure that we go ahead and get steps 4 and 5 on page lh of their checklist before LOS here. And then, as soon as we get into attitude, we can take a look at all this before we go LOS. We got about 16 minutes.
CMP: Okay, understand. That's steps 4 and 5 on page 14.
CC: And, Apollo 15; Houston. Also, go ahead and get the P30 and et cetera, et cetera.
CMP: Roger. Understand. Go ahead and get the P30 in the I_M.
CC: And there is no update to the Tig. It's good as given to you earlier.
CMP: Roger. Understand. T. is good. zg
CC: And, Al, stand by to turn the GAMMA RAY, GAINSTEP, SHIELD, on.
CMP: GAMMA RAY, SHIELD, on.
CC: Okay, MARK ON, and let's take the MAP CAMERA_ ON switch to STANDBY and the MAP CAMERA, IMAGE MOTION, OFF.
CMP: Okay. MAP CAMERA, STANDBY, IMAGE MOTION, OFF.
CC: That about cleans us up, Al.
CMP: Okay, Ed. Thank you much for your help.
LMP: Oh, Ed, I'm back on comm, over in the Falcon.
CC: Okay, Jim. Sounds good. Should be in attitude in Just a minute. And your angles 205 and 70, as in the Flight Plan, should be good, and we're about 13 minutes from LOS.
LMP: Okay. Do you have any updates for me before we have LOS?
CC: Negative. All we wanted to do was Just - the guidance systems state vector's okay and con- figured before LOS, and I don't believe we have an update. I '11 check.
CC: Falcon, Houston. We'd Just like to complete down through step i or 2 of configure AGS before LOS. And, Endeavour, if you can give us an ACCEPT, we'11 shoot you an up-link before LOS.
CMP: Okay, getting ACCEPT.
LMP: Falcon copies.
CMP: You got ACCEPT.
CC: Ed, can you get for - the P30 load here for me as I go through it?
CC: Okay, stand by 1. Okay. Go ahead. Got the first one.
CC: Okay, how does that look?
CC: Looks good here, Jim.
LMP: Okay, I'11 PRO on this one.
LMP: Okay, I'm going to go to P00, Ed.
CC: Roger, Jim. That one looks okay, too. I don't see much of it.
CC: That's right. Okay, do we have a GO for close- out ?
CC: Give us a 470 readout on the DEDA, please.
LMP: Okay. You have it.
CC: Okay. And, Jim, can you verify that you've done all of step 2 on the camm?
CC: Yes, I meant SLEW on the TRACK MODE.
CC: Okay, Jim. You're GO for closeout. The next time we see the Ik4, you'11 all be buttoned up. So sug- gest you make a very careful check of the items from now on.
CC: Okay; thank you, Ed.
CC: And, Endeavour. It's your computer.
CC: Okay, Endeavour, Houston. We're a minute and 20 seconds from LOS. Your ascent CAPCOM's going off duty, and I'11 see you back on Earth. It's been a lot of fun getting you up there.
CMP: Okay, Ed. You're - thanks a million, pal. You've been a great help, and it was fun t_lking to you.
LMP: Hey, Ed; Falcon. Looks like we Just about got things cleaned up here.
CC: Very good, guys. We'11 see you in a few days. Thanks a lot.
CMP: Okay, Ed, thank you.
CDR: Hello, Houston; 15. How are you?
CC: Roger. Doing fine down here. Can you fellows confirm LM closed out and ready for Jet?
CDR: Roger. LM's closed out, and we're Just now run- ning our pressure integrity check, and we'11 be all set in a Jiffy.
CDR: Okay, we are goingto be a few minutes here. We got to put some LCG plugs in our suits, and it's going to take probably about 10 or 15 minutes to get all that done.
CC: Okay, and we'd like a verification from A1 that X-RAY/ALPHA X-RAY is in STANDBY and COVERS are CLOSED before Jet and SEP burn.
CDR: Okay. We'11 get that for you when we get squared away here.
CDR: Houston, Apollo 15. Go.
CC: Say, Dave, beautiful Job there today all the way around. Hey, one quick question - how come you guys need plugs for those suits?
CDR: Well, because, apparently, the LCG connection on the inside won't hold - an air seal, so we're getting them taken care of with these special - extra little blue plugs we got that are air tight on the inside.
CDR: At least that's our first guess of - of why we didn't get a good suit integrity check or didn't even get a good buildup in the suit pressure.
CC: Roger. We - we had a complete misunderstanding on that, so that's the reason I asked the ques- tion, because we thought those plugs only were We're required when the LCG was not on. trying to crack that one for you down here, Dave. There's something screwy here.
CDR: Okay. Well, we'11 put these plugs in and run another pressure integrity check and see how it works.
CC: Roger. Tape ll5/1
CC: Roger, Dave. You guys talking about inside plugs or outside plugs.
CDR: Inside plugs.
CDR: Okay, Houston, 15. We've got a good SUIT CIRCUIT now.
CC: Roger. We've been looking at it; copy, agree.
CC: And, 15, we're still looking for an X-RAY/ALPHA COVER door, CLOSED.
CDR: Okay. Stand by l, Houston.
CDR: Okay, Houston. The X-RAY/ALPHA door is CLOSED.
CMP: Okay, we're ready to ARM the LOGIC.
CMP: Okay. LOGIC 1. LOGIC 2.
CC: Roger. You're GO for PYRO ARM.
CMP: 15, LM/CM DELTA-P is 2.5 - 2.0, excuse me.
CC: Copy, 2.0.
CC: Roger, 15. Go.
CDR: Okay, the LM/CM DELTA-P doesn't look exactly right to us. What do you think?
CC: 15, Houston. We'd like to get another pound out of there. We're showing about 3.5 in there.
CDR: Okay. We had a suspicion that possibly the LM overhead dump valve was open, and it might be.
CC: We don't think so down here.
CDR: Okay. Well, we'11 go to TUNNEL VENT for a little longer, must Just be slow then; we've been in it for probably about 15 minutes.
CC: 15, what position are you in when you're reading that out, in VENT or in DELTA-P?
CDR: It's up to about 2.B now, and I've been holding it in TUNNEL VENT.
CC: 15, we'11 take that. It'd take too long to get it _ down, we believe. So let's press on with JETT at that pressure.
CDR: Okay, well, the strange thing about it is that we had it up to about - oh 2.7 or 2.8 at one time and then went back to LM/CM DELTA-P, and for some reason it built back up in the _unnel. And, I guess the only conclusion we could come to was - from the LM, because the hatch is pretty simple and secure in here.
CC: Dave, we think that the increase in the cabin pressure during the suit integrity check could have raised it frc_ - from your side.
CDR: Well, okay, that's - that's true.
CC: Bye, Dave; confusion reigns down here.
LMP: CDR Could you see any ch - Well, I guess it sort of does up here, too. I wonder if you see any dif- ference in the - you can't read the t,_nnel, tho,_h, can you?
CC: And, 15; this is Houston. We'd like to verify that you did get a good hatch integrity check back there a ways.
CDR: Yes, that's firm. We got a good hatch integrity check, but - I guess what I'm thinking is there's - you know, there could be something in the seal there. And perhaps the thing to do would be to repressurize the tUnnel and pull the hatch down, and take a good close look at the seal and then stick it back in. It shouldn't take too long.
CC: Apollo 15, Houston. That seems to be about the best conclusion we can come to down here, but we're - kind of like to go into a hold briefly. Another indication is that we would - we are seeing the I2_ cabin holding steady and not using any oxygen from the ascent tanks, which seems to say that we're not leaking into the tunuel from the LM.
CC: 15, Houston. We'd like to verify that the pressure equalization valve is closed.
CDR: That's verified; it's closed and on the yellow strips.
CC: And, 15, we'd like to back out of your PYRO ARM situation right now.
CMP: Okay, Houston, 15. PYRO ARM is SAFE, LOGIC is OFF, and the PYRO ARM circuit breakers are pulled.
CC: 15, can you give us a LM/CM DELTA-P reading at this time; please?
CDR: Okay, right now it's 3.0.
CC: Copy, 3.0.
CDR: And, I've had the valve in TUNNEL VENT for the last 5 minutes or so.
CC: Apollo 15, Houston. Recommendation right now is to Stop the - the LM TUNNEL VENT, and then we will sit and monitor the CM/IAM DELTA-P for a short while to see what happens to it. And, after that, we're still considering opening up the tunnel to check the seal. Over. LM/CM
CDR: Okay, we're in DELTA-P right now, and it's reading about 3.1.
CC: Copy, 3.1. B/D
CC: 15, we'd like to pull the ROLL Jets. B/D
LMP: Roger. ROLL Jets coming off.
CC: And, 15, if one of you has a chance, would you put X-RAY to STANDBY, please?
CDR: Roger X-RAY to STANDBY.
CDR: Okay, Houston; it's in STANDBY.
CC: 15, Houston. You give us a reading now on that?
CMP: Okay, Houston; stand by 1.
CMP: It's Just a little under 3.1, Just a - just a hairline. 115/5 Tape
CC: Roger; copy. And we're still looking at the possibility of opening the hatch. We're Just trying to - right now, trying to understand the the configuration we're in.
CDR: OkaY, we'11 stand by.
CC: And, 15; Houston. Could we have another reading in 10 minutes?
CDR: Well, it's reading right now Just about the same that it was when I last called you.
CC: Roger; copy. There's certainly enough uneasiness down here that we think we ought to proceed back through and open both the command module hatch and the I_ hatch, check the seals on both and the relief valves on both, proceed back through that doing - doing those checks, because there could be a very slight leak from the IAM that the telemeter guys would not see at - for this small volume in the tunnel. Over.
CDR: Roger. We sort of think that's a good idea, too. We'11 proceed.
CC: Roger. Keep us posted when convenient.
CC: 15, Just in case you haven't got the idea, when I said check the seals, I mean clean them, too.
CDR: Roger. Understand. We'11 make sure they're good and clean.
CDR: Okay, Houston; 15. Both hatch seals are clean, and both hatches are now closed and locked. Do you want to vent the tunnel again?
CC: Roger. Go ahead, Dave. Thank you.
CC: And, 15, are you guys all still fully suited?
CDR: Roger. We did not break down the suits; we're still locked up.
CDR: And the LM overhead dump valve was verified in auto.
CDR: Okay, Houston. We're 1.3 on - DELTA-P and coming - coming up.
CMP: Okay, Houston; we're about 2.2.
CMP: And, Houston, do you want to go to 3 and let it stabilize there?
CC: I guess we'11 do per the checklist which is 3.5, right?
CDR: Well, not really. Our checklist says before I/_ Jettison only, I_ TUNNEL VENT valve, TUNNEL VENT at least 10 minutes, period.
CDR: Course that's after the hatch integrity check. If we want to go ahead and run through the full hatch integrity check, then we'd run up to 3.5 and then run another 10 minutes, I guess.
CC: Yes, that's the point, Dave. We want to run a complete ha - hatch integrity check; in fact, we'11 proba - we may ask you to run it longer than usual.
CC: Obviously, what we're thinking about here is a bad _ hatch seal, so we're particularly interested in that.
CC: And, 15, a reminder. When you're on the back side, LM is still in 5-degree dead band, so play it cool with the c........ and module.
CDR: Roger. Pase 1233.
CDR: _ And, 15, what we'd like to see you do is leave %hat tunnel at 3.5 for the entire baCk'Side paSs, and we'11 see what happens to that leak rate. That gives us a nice, long leak check on the hatch. And, we'11 be satisfied with that DELTA-P for JETT, if that's the way it works out on the other side.
CDR: Okay. And, I guess in that case, we'11 probably break the suits down and then run another suit check before we see you around the corner. So -
CC: Okay, we'11 buy that.
CDR: It's about time for dinner.
CC: I knew there was a reason.
CDR: Roger. Okay, we're about 3.2 now on the DELTA-P. We'11 leave LM in VENT.
CC: Roger. I understand; 3.2 and still venting.
CC: Dave, stand by on taking your suits off; if you haven't taken them off already.
CDR: Okay. We hadn't planned to take our suits off; we're Just going to break off the helmets and gloves so we could get something to eat.
CC: Roger. But stand by on breaking the suits down; because it's a debate as to whether we want to do another suit integrity check.
CC: 15, press on. You may - you are permitted to break the suits down, but do not do the suit integrity check until you come back around the other side; we can take a_other look at that tunnel. Over.
CDR: Roger; understand. We'11 break them down and hold off until we see you on the other side.

CDR: I'd say LN CM DELTA-P is off scale high.
CC: Roger. And how did the hatch integrity check go?
CDR: Well, we've Just had it in tunnel vent all the - the way around the back side as I think you suggested.
CC: 15, did you have a look at holding it in DELTA-P to see how the - see how it was holding on that?
CDR: No, we Just left it in TUNNEL VENT all the way around the back side. I - That's what we'd thought you'd said to do. We can check it now.
CC: 15, why don't you bring it up to 3.5, and let us watch it for a while. I think we garbled some - and you watch it. I think we garbled something there.
CDR: Okay. Our understanding was to let it go all the way, and then you get a good look out on this side. So we'11 bring it up to 3.5.
CC: 15, Houston. Two items; one, we want to make sure that you're aware that we cannot read the tunnel pressure, and so we're depending upon your read- outs of this DELTA-P to give us the confidence here in the hatch integrity. One other item that we do know, is that during all that period when the tunnel was vented, our 02 flow was off-scale low, which does give us some confidence in the integrity of the hatch. And, meanwhile, we're waiting for your ca]] on a 3.5 reading so we can begin a hatch integrity check. Over.
CDR: Mark. Two minutes and 3.5 plus or minus 0.
CDR: And - and I think we had the same confidence, Bob. We noticed the low 02 flow also. The only ques- tion we had was, why did the DELTA-P change?
CC: That's the same question that was bothering us.
CDR: But, it's steady at 3.5, and has been now for about 2 and a half minutes.
CC: Okay, 15. This is Houston. We'd like to run that hatch integrity check to about 5 minutes total, because of what we suspect was the problem before. And, if it passes at that point, welll press on, per the Flight Plan, for following the normal steps. And you can plan, if we have time for it, we're looking for a Jet at 179:30, at the present time. Over.
CDR: Roger. 179:30, and we'11 give you a call at the 5-minut e point.
CDR: Okay, Houston. There's 5 minutes at 3.5 and it looks solid.
CC: Roger, Dave. Let's press on with a nominal time line.
CDR: And, Houston. Are you happy with 3.5 or would you like to bleed it down a little more?
