"My Luftwaffe is invincible...And so now we turn to England. How long will this one last — two, three weeks?" – Hermann Göring, June 1940

Given its unique strengths and distinctive weaknesses by the personal quirks of the men who developed it, the Luftwaffe initially overwhelmed the more conservative, outdated military aviation of other countries. Its leaders embraced such concepts as the dive-bomber, which proved both utterly devastating and extremely useful for supporting the sweeping, powerful movements of Blitzkrieg, while other martial establishments rejected dive-bombers as impractical or even impossible. Though the superb fighting qualities of highly trained and motivated German soldiers, and the Third Reich's technological superiority in tank and weapon design, also had crucial roles to play, the Luftwaffe represented the key element making the successes of all other branches possible.

Ultimately, the loss of the Luftwaffe's domination was due in most part to the efforts of Britain's Royal Air Force, which prevented Nazi Germany from conquering Britain on their own. The Battle of Britain, fought throughout the summer and early autumn of 1940, was unquestionably epic in scope. The largest air campaign in history at the time, the vaunted Nazi Luftwaffe sought to smash the RAF as a prelude to German invasion, leaving the British public and its pilots engaged in what they believed was a desperate fight for national survival. The fate of the free world, at least as Europe knew it, hung in the balance over the skies of Britain.

Of course, the RAF was instrumental in other ways during the war. The RAF supported Allied forces all over the world, from Norway to Burma to Tunisia, and the RAF conducted devastating bombing campaigns against German industry and cities. In the end, the Allies emerged victorious, even as Britain fell behind other leading nations in air technology.
