The first true jet fighter was the twin-engine Heinkel He-280, first flown 30 March 1941. The He-280 featured such advances as a tricycle landing gear and a compressed-air ejection seat, but its airframe belonged to the piston-engine era.
Heinkel He-280. Less than two weeks later, on 27 March, Erhard Milch cancelled the project. The Jumo 004-powered Me 262 appeared to have most of the qualities of the He 280, but was better matched to its engine. Heinkel was ordered to abandon the He 280 and focus attention on bomber development and construction, something he remained bitter about until his death.
