Flight

Launch from Cape Canaveral (KSC); landing on Edwards AFB.

Launch was originally scheduled for 20 November 1989, but was delayed because of suspect integrated electronics assemblies which control ignition and separation of the Shuttle's solid rocket boosters.

S. David Griggs, the originally scheduled pilot for this mission, died in a plane crash 5 months prior to the shuttle launch. He was replaced by John Blaha.

Fifth mission dedicated to Department of Defense; deploying of reconnaissance satellite "Big Ear" (Magnum 2; USA-48), a secret Magnum ELINT (ELectronic INTtelligence) satellite. Gregory became first afro-american spacecraft commander.

Landing was postponed for a day because of strong winds at the landing site.
