Launch Info: Orbiter - Columbia 102-19 Pad 39B KSC (MLP-3) - STS-75 is 50th
Return-To-Flight mission. First American mission to fly on Leap Day, 29 February.
Landed on runway 33, KSC/SLF. 29th KSC landing. On FD 3 a one day extension was
made following data communication dropouts with the TSS & ground, a second one day
extension was considered during the flight but was cut following OPS-8 computer
problems. Four landing opportunities (2 KSC/2 EAFB) were waved off due to weather
on 8 March, forcing aone day extension. On 9 March, the first available KSC opportunity
was waved off due to cloud cover over the SLF. Guidoni had no formal Backup this flight.
Allen, Chang-Diaz, Hoffman & Nicollier all flew together on TSS-1 (STS-46), with
Guidoni serving as back-up on that mission to Franco Malerba.
