Time		Crew	Crew
(Min:Sec)	Member	Comment
T-2:05		MS2	Would you give that back to me?
T-2:03		MS2	Security blanket.
T-2:02		MS2	Hmm.
T-1:58		CDR	Two minutes downstairs; you gotta watch running down there?
	(NASA: Two minutes until launch.)
T-1:47		PLT	OK there goes the lox arm.
	(NASA: Liquid oxygen supply arm to ET.)
T-1:46		CDR	Goes the beanie cap.
	(NASA: Liquid oxygen vent cap.)
T-1:44		MS1	Doesn't it go the other way?
T-1:42		Laughter.
T-1:39		MS1	 Now I see it; I see it.
T-1:39		PLT	God I hope not Ellison.
T-1:38		MS1	I couldn't see it moving; it was behind the center screen.
	(NASA: Obstructed view of liquid oxygen supply arm.)
T-1:33		MS2	Got your harnesses locked?
	(NASA: Seat restraints.)
T-1:29		PLT	What for?
T-1:28		CDR	I won't lock mine; I might have to reach something.
T-1:24		PLT	Ooh kaaaay.
T-1:04		MS1	Dick's thinking of somebody there.
T-1:03		CDR	Unhuh.
T-59		CDR	One minute downstairs.
	(NASA: One minute until launch.)
T-52		MS2	Cabin Pressure is probably going to give us an alarm.
		(NASA: Caution and warning alarm. Routine occurrence during prelaunch.)
T-50		CDR	OK.
T-47		CDR	OK there.
T-43		PLT	Alarm looks good.
	(NASA: Cabin pressure is acceptable.)
T-42		CDR	OK.
T-40		PLT	Ullage pressures are up.
	(NASA: External tank ullage pressure.)
T-34		PLT	Right engine helium tank is just a little bit low.
	(NASA: SSME supply helium pressure.)
T-32		CDR	It was yesterday, too.
T-31		PLT	OK.
T-30		CDR	Thirty seconds down there.
	(NASA: 30 seconds until launch.)
T-25		PLT	Remember the red button when you make a roll call.
	(NASA: Precautionary reminder for communications configuration.)
T-23		CDR	I won't do that; thanks a lot.
T-15		CDR	Fifteen.
	(NASA: 15 seconds until launch.)
T-6		CDR	There they go guys.
	(NASA: SSME Ignition.)
		MS2	All right.
		CDR	Three at a hundred.
	(NASA: SSME thrust level at 100% for all 3 engines.)
T+O		MS2	Aaall riiight.
T+1		PLT	Here we go.
	(NASA: Vehicle motion.)
T+7		CDR	Houston, Challenger roll program.
	(NASA: Initiation of vehicle roll program.)
T+11		PLT	Go you Mother.
T+14		MS1	LVLH.
	(NASA: Reminder for cockpit switch configuration change.
	Local vertical/local horizontal.)
T+15		MS2	(Expletive) hot.
T+16		CDR	Ooohh-kaaay.
T+19		PLT	Looks like we've got a lotta wind here today.
T+20		CDR	Yeah.
T+22		CDR	It's a little hard to see out my window here.
T+28		PLT	There's ten thousand feet and Mach point five.
	(NASA: Altitude and velocity report.)
T+30		Garble.
T+35		CDR	Point nine.
	(NASA: Velocity report, 0.9 Mach.)
T+40		PLT	There's Mach one.
	(NASA: Velocity report, 1.0 Mach.)
T+41		CDR	Going through nineteen thousand.
	(NASA: Altitude report, 19,000 ft.)
T+43		CDR	OK we're throttling down.
	(NASA: Normal SSME thrust reduction during maximum dynamic pressure region.)
T+57		CDR	Throttling up.
	(NASA: Throttle up to 104% after maximum dynamic pressure.)
T+58		PLT	Throttle up.
T+59		CDR	Roger.
T+60		PLT	Feel that mother go.
T+60		Woooohoooo.
T+1:02		PLT	Thirty-five thousand going through one point five.
	(NASA: Altitude and velocity report, 35,000 ft., 1.5 Mach.)
T+1:05		CDR	Reading four eighty six on mine.
	(NASA: Routine airspeed indicator check.)
T+1:07		PLT	Yep, that's what I've got, too.
T+1:10		CDR	Roger, go at throttle up.
	(NASA: SSME at 104 percent.)
T+1:13		PLT	Uhoh.
T+1:13		LOSS OF ALL DATA.
