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).
And so, in September 13 2007, the SSC Ultimate Aero made its run for the record. Using FIA rules of getting the average speed from 2 runs in opposite directions, it got an average top speed of 256 mph, enough to obtain the world record that even Guinness recognizes as legit.
