Col John Glenn piloted the Mercury "Friendship 7" spacecraft in the first United States human manned orbital flight on 20 February 1962. Electrical and electronic systems invented by McDonnell engineers made his spaceflight possible. Among the key contributions were navigation and control instruments, autopilot, rate stabilization and control, and fly-by-wire (FBW) systems.
