Military aircraft - Jet Engines, Supersonic Flight, Stealth | Britannica
The He 178, the first jet-powered aircraft, flew on Aug. 27, 1939, nearly two years before its British equivalent, the Gloster E.28/39, on May 15, 1941. Through an involved chain of events in which Schelp’s intervention was pivotal, Wagner’s efforts led to the Junkers Jumo 004 engine.

Jet Engines, Civil Aviation, Air Travel - Britannica
With their continuous rotary motion, jet engines were mechanically simpler and smoother than reciprocating pistons with their rough pounding. Jet engines developed rapidly and by 1950 had reached levels of power that were impossible with piston engines.
Military aircraft - Transonic Flight, Supersonic Speed, …
As the first generation of jet fighters entered service, many aerodynamicists and engineers believed supersonic flight a practical impossibility, owing to transonic drag rise or compressibility, which threatened to tear an aircraft apart.
MiG | Soviet Cold War Era Aircraft | Britannica
The early MiG aircraft were propeller-driven fighters produced in moderate numbers during World War II. The MiG-9, which first flew in 1946, did little more than apply jet propulsion to a piston-engine airframe; but the MiG-15 , built with swept-back wings derived from German wartime research and powered by a copy of a Rolls-Royce engine ...
