Video: 'STS-51F launch, abort & landing (7-29-85)'
(Monday, July 29, 1985, 21:00:00 UTC) — The space shuttle Challenger began an 8-day mission today that got off to a shaky start: the spacecraft achieved a safe orbit even though one of its main engines shut down prematurely after lift-off.
It was the first major malfunction during ascent in the 19 flights of the shuttle program.
