The Germans started the Second World War with what was then the best fighter in the world, the Messerschmitt Me 109. But a superior fighter appeared during the Battle of Britain: the British Supermarine Spitfire. She played a major role in the fact that the Germans could not defeat England.
A new type of aircraft was supposed to restore control of the air: the Me 262 jet fighter. However, interventions by Hitler meant that the Germans’ lead melted away. When the Me 262 flew its combat missions, the Western Allies were already at or about to build their own jets. Only the Soviets lagged behind in the race. Your air force was not really taken seriously by the West anyway.
A mistake. This was evident when the pilots from the west came across the MIG-15 and its Soviet pilots via Korea. This MIG brought an abrupt end to the era of the first fighter jets.
Civil aviation followed astonishingly quickly. The four-engined British de Havilland DH.106 Comet was the first mass-produced jet airliner in the world. The first maiden flight took place on July 27, 1949.
