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).
But Consumer Reports has changed the ground rules: While the federal government requires a 30 mph frontal crash for car seats, Consumer Reports ran it at 35 mph and 38 mph for side-impact crashes, the same speeds used for new car tests.
