ww2dbaseThe He 280 design was started by Heinkel on its own initiative to further its jet research program despite its previous jet fighter effort, the He 178 program, had largely been ignored by the German Aviation Ministry. The project was placed under the head designer Robert Lusser. The first prototype was completed in the summer of 1940, but delays in the jet engines forced the maiden flight, on 22 Sep, to be an unpowered one, testing its aerodynamics by gliding. On 30 Mar 1941, test pilot Fritz Schäfer conducted the first powered test flight with the second prototype example; this prototype aircraft became the first turbojet-powered fighter aircraft to fly in the history of aviation. A week later, on 5 Apr, a He 280 demonstration flight was conducted for Ernst Udet from the Aviation Ministry, who was not impressed. As Heinkel continued on with this project despite the lack of interest from the military, it was continuously plagued by engine problems, so much so that in 1942 the Aviation Ministry ordered the firm to abandon its HeS 8 and HeS 30 jet engine projects so that they could focus only on the HeS 011 jet engine project. The next major demonstration took place on 22 Dec 1942, where a mock dogfight was staged. It finally convinced the Aviation Ministry to issue an order for 20 aircraft for testing with a tentative order for 300 production aircraft should the first 20 be tested successfully. On 16 Mar 1943, a He 280 prototype aircraft took flight using a pair of a competitor's engines (Jumo 004 jet engines built by Junkers); although the test was relatively successful, the prototype's performance was lagging behind the Me 262 jet fighter built by Messerschmitt, which was equipped with the same Jumo 004 jet engines. On 27 Mar, the entire project was canceled on the order of Erhard Milch. Heinkel was ordered to focus on bomber development for the remainder of the war.

Helmut Schenk, Luftwaffe test pilot used the
first ever ejection to escape from an aircraft.
He ejected from his disabled Heinkel He 290
V-1 jet fighter on January 14, 1942.
