Thirty-three years ago today, at 7:00 AM Florida time, the Space Shuttle with the orbiter Columbia launched for the first time.
So it's only appropriate that this week's Retro Saturday film is Space Shuttle: A Remarkable Flying Machine, a NASA documentary about that first flight.
STS-1 was the first time that NASA launched a crewed flight without doing an unmanned test before. Although theoretically possible, NASA didn't attempt to launch an orbiter and pilot it by remote control to landing.
So astronauts John Young and Bob Crippen assumed the risk, spending two days in orbit.
