The Messerschmitt Me262was the world's first operational jet powered fighter aircraft. Its design had actually started before the beginning of the Second World War, but it wasn't until the war started to turn against the Nazi regime that the development work was speeded up. Problems with the new axiol-flow turbojet engines as well as interference from the German heirachy delayed the project still further, but by April 1944 when the machine was finally introduced into service it was a giant leap forward in flight performance over contemporary piston engine fighters. Using its advanced aerodymanic as well as the powerful twin turbojets, the Me262 had incredible straight line performance. It was able to out accelerate anything the Allies had and its four 30mm cannons also packed a powerful punch.
