It reveals the comments of Commander Francis R.Scobee, Pilot Michael J. Smith, Mission Specialist 1 Ellison S. Onizuka, and Mission Specialist 2 Judith A. Resnik for the period of T-2:05 prior to launch through approximately T+73 seconds when loss of all data occurred. The operational recorder was automatically activated at T-2:05 and normally runs throughout the mission. During the period of the prelaunch and the launch phase covered by the voice tape, Mission Specialist 3 Ronald E. McNair, Payload Specialist 1 S. Christa McAuliffe, and Payload Specialist 2 Gregory B. Jarvis were seated in the middeck and could monitor all voice activity but did not make any voice reports or comments. This transcript was released following the accident on January 28, 1986. A copy of the document is also available in the NASA Historical Reference Collection, History Office, NASA Headquarters, Washington, DC.<\/em><\/p>\n\n\n\n<div style=\"height:56px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>CDR:<\/strong> Scobee<br><strong>PLT: <\/strong>Smith<br><strong>MS 1: <\/strong>Onizuka<br><strong>MS 2:<\/strong> Resnik<\/p>\n\n\n\n<p>(The references to “NASA” indicate explanatory references NASA provided to the Presidential Commission.)<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Time (Min:Sec)<\/th><th>Crew Position<\/th><th>Crew Comment<\/th><\/tr><\/thead><tbody><tr><td>T-2:05<\/td><td>MS 2<\/td><td>Would you give that back to me?<\/td><\/tr><tr><td>T-2:03<\/td><td>MS 2<\/td><td>Security blanket.<\/td><\/tr><tr><td>T-2:02<\/td><td>MS 2<\/td><td>Hmm.<\/td><\/tr><tr><td>T-1:58<\/td><td>CDR<\/td><td>Two minutes downstairs; you gotta watch running down there?<\/td><\/tr><tr><td>(NASA: Two minutes till launch.)<\/td><td> <\/td><td><\/td><\/tr><tr><td>T-1:47<\/td><td>PLT<\/td><td> OK there goes the lox arm.<\/td><\/tr><tr><td>(NASA: Liquid oxygen supply arm to ET.)<\/td><td> <\/td><td><\/td><\/tr><tr><td>T-1:46<\/td><td>CDR<\/td><td>Goes the beanie cap.<\/td><\/tr><tr><td>(NASA: Liquid oxygen vent cap.)<\/td><td> <\/td><td> <\/td><\/tr><tr><td>T-1:44<\/td><td>MS 1<\/td><td>Doesn’t it go the other way?<\/td><\/tr><tr><td>T-1:42<\/td><td> <\/td><td>Laughter.<\/td><\/tr><tr><td>T-1:39<\/td><td>MS 1<\/td><td>Now I see it; I see it.<\/td><\/tr><tr><td>T-1:39<\/td><td>PLT<\/td><td>God I hope not Ellison.<\/td><\/tr><tr><td>T-1:38<\/td><td>MS 1<\/td><td>I couldn’t see it moving; it was behind the center screen.<\/td><\/tr><tr><td>(NASA: Obstructed view of liquid oxygen supply arm.)<\/td><td> <\/td><td><\/td><\/tr><tr><td>T-1:33<\/td><td>MS 2<\/td><td>Got your harnesses locked?<\/td><\/tr><tr><td>(NASA: Seat restraints.)<\/td><td> <\/td><td><\/td><\/tr><tr><td>T-1:29<\/td><td>PLT<\/td><td>What for?<\/td><\/tr><tr><td>T-1:28<\/td><td>CDR<\/td><td>I won’t lock mine; I might have to reach something.<\/td><\/tr><tr><td>T-1:24<\/td><td>PLT<\/td><td>Ooh kaaaay.<\/td><\/tr><tr><td>T-1:04<\/td><td>MS 1<\/td><td>Dick’s thinking of somebody there.<\/td><\/tr><tr><td>T-1:03<\/td><td>CDR<\/td><td>Unhuh.<\/td><\/tr><tr><td>T-59<\/td><td>CDR<\/td><td>One minute downstairs.<\/td><\/tr><tr><td>(NASA: One minute till launch.)<\/td><td> <\/td><td> <\/td><\/tr><tr><td>T-52<\/td><td>MS 2<\/td><td>Cabin Pressure is probably going to give us an alarm.<\/td><\/tr><tr><td>(NASA: Caution and warning alarm.
