Ejector seat Tests were recently conducted for the ejector seat system of the F-35 Lightning II, at speeds of up to 600 miles per hour.

Scientists said the ejector seat passed all its tests during 30 test runs made in Britain, France and the U.S.

‘Ejecting from an aircraft like F-35 typically takes no more than three seconds from the time the ejection handle is pulled to the pilot being on a parachute,’ BAE Systems’ Rick Whitaker told The Sun.



The escape system, used in emergency situations, ensures pilots can eject safely and will be fitted to all 3000+ F-35 aircraft which will be flown by armed forces across the globe.
