Launch Info: Orbiter - Challenger 099-10 Pad 39B KSC (MLP-2) - First use of
Pad 39B. First attempt of 27 January was scrubbed due to a hatch closing fixture, which
had to be forcibly removed at T-9 minutes, resulting in a scrub after crosswinds
developed at the SLF. Launch was delayed 2 hours due to a Launch Processing System
failure in the fire detection system. The flight ended at T+73 seconds due to a burn-
through in the RH SRB, and the ET/Orbiter were destroyed in the explosion. The SRB's
were destroyed by Ranges Safety Officer (RSO) at T+110 seconds.
