P: Roger. CONFIDENTIAL 927 looking real good down here on the ground. This is the last pass for the afternoon, so we'11 be seeing you tomorrow, and we'11 be standing by. HAWAII no further instructions for you. Standing by. CALIFORNIA Measurement here. Let me know when you need some quiet to do that. get to Texas to do that. And let me know when you need me to stop talking so you can work on your measurement. Rate Command for Retro and then Single-Ring Rate Command for the reentry, and he found that he had to cut in the other ring because he ran out on RCS A. He had to cut in the second ring about at the end of blackout, so we wanted to let you know about that. We noticed that you are planning to use Single-Ring Direct on your reentry and we'd like to concur on that, and then if you have to use more authority, you might try Reentry Rate C_-,,._nd,and eventually, if you have to, of course, Zero-Ring Rate Command. But we wanted to let you know that he did need both rings because he ran out of the first one. procedure of reentering. discuss this shirt-sleeve environment business with you again. Make sure we have this specific question that we had left here answered. I'11 wait till after your D-4 Measurement. TEXAS do your experiment whenever you're ready. environment evaluation with you a little bit further. Like to ask specifically in the second configuration that we had you in awhile this morning - we understood that the air was sort of stagnant on your side, Jim, but we'd like to understand also whether the fan - cabin fan - being on made it okay, or whether there w_s still some stagnation even with the fan on. cabin fan on. Have, at any time, you had your inlet and outlet hoses in a - in roughly the same position - same proximity - in other words, very close together for the air to come out and also go back in? We wonder, if you do that, would the circulation be adequate? all be alined if we have the inlet and outlet hoses fairly close together. I think the situation will go just between them, that we will find stagnation points. would like you to try that for a short period, because that is the present configuration in Apollo, and we want to make certain about this so that we can tell them, if it is necessary to change it. like poor design, based on what we found up here. inlet and the exit, F31iot. we want to make sure that we can definitely state this. Attitude Shield gage, and as far as I'm con- cerned, that's the end of the Attitude Shield for experiments. You have some reason to keep it different from that? i percent is tough to see. about twice as much fuel because you can't get a small enough impulse in. T/M? ahead and get - maybe we can get that photo of the window measurement now. watching your fuel very closely and we would feel quite confident to let you go down to 5 percent, if you are willing to. If you want to stop here, that's all right, but we feel you're quite adequate if you go on down to 5 percent. platform tomorrow? Nobody knows - - window. GAm_ni VII. I have another item to discuss with you. to me if you want to. environment evaluation, when you put the hoses CONFIDENTIAL 931 together, you might also evaluate that with - you might evaluate that with fan on and fan off. have 9 pounds of MMH remaining. If you went ahead and took it down to 5 percent, you would have 7 1/2 pounds remaining. T/M out on that parameter, but we are still receiving T/M. not ? voice tape. our voice tape also. that we have Just seen the pictures, some of the pictures that GT-VI brought back; Just a very few of them have been processed so far, but they are really outstanding' You Just look great sitting up there ' we were telling you about? pletely precise in every detail. We can see the D-d instruments sticking out the sides. Can see your whole nose section; just every little detail is as clear as a bell. minute ago - the little bit that's been developed so far. We can see the scanners working in it. It's Just tremendous film! networks - live. pictures are really great, Frank: film this afternoon, and then stow it up.
