The testing process is extensive and rigorous; the software on the Shuttle is often considered to be among the most bug-free of operational systems.

The FIRST SAIL CDR (Commander - left seat) was James E. Westom/Rockwell International, retired Major USAF. His service as SAIL CDR started in the Approach and Landing test phase, where the orbiter (flying part) was launched off the top of the NASA C-747 vehicle to prove it could fly on its own in the atmosphere. Maj Westom's duties were from 1974-1989, when he had to retire early for family medical support.
