What happened
British engineer Frank Whittle and German engineer Hans von Ohain developed jet engines independently and almost simultaneously in the 1930s; von Ohain received his jet engine patent on November 10, 1935, and his engine first ran successfully in a test rig in March 1937, narrowly ahead of Whittle's April 1937 test run. Von Ohain's engine powered the Heinkel He 178, which flew on August 27, 1939, becoming the world's first jet aircraft to fly, days before Germany invaded Poland. Germany pushed the technology into combat first: the Messerschmitt Me 262, powered by Junkers Jumo 004 engines, entered operational service on July 26, 1944, becoming the first operational jet fighter in history and shooting down more than 500 Allied aircraft before the war's end, despite engines that typically lasted only 10 to 25 hours before burning out.
Why it matters
The Me 262 arrived too late and in too few numbers, several hundred built, to change the outcome of the war, but it proved jet propulsion's decisive speed advantage over piston-engine fighters in actual combat, guaranteeing every air force on earth would rebuild around jet engines within a decade. The wartime parallel development by Whittle in Britain and von Ohain in Germany also meant the jet age arrived simultaneously on both sides of the conflict rather than as a one-country monopoly.
How we know
The parallel development timelines of Whittle and von Ohain's engines, and the Me 262's combat service, are documented in U.S. Air Force-affiliated aerospace history publications drawing on wartime German and British engineering records.
