In the early 1960s, deployment of rocket-powered ejection seats designed for use at supersonic speeds began in such planes as the Convair F-106 Delta Dart. Six pilots have ejected at speeds exceeding 700 knots (1,300 km/h; 810 mph).
The average freefall speed is 120-130 mph. In a student jump from over 2 miles up, this allows you to fall for about 45 seconds before you will reach deployment altitude. The skydiver's weight or body position can alter this speed. The freefall speed record is over 330 mph!
