Lessons Learned - Flight Schedules
Year: 1992
Abstract: Description of Driving Event:
The original STS operations baseline plan defined required capabilities for the STS system before it was designed. The operational system would fly 6 flights the first year, 15 the second, 24 the third, and by the sixth year a total of 60 flights per year. To meet this flight rate, turnaround was to be completed in 14 days. The vision of the operational space shuttle was clearly much larger than the resource base eventually established to create the capability. The 1985 mission operations were successful in spite of significant remanifesting and perturbations. However, all trends prior to the STS 51-L mishap indicated that the milestones required to support preparations for the 1986 flight schedule were not being met.
