1945 Messerschmitt 262A-1

• 1945 – World War II: a defecting German pilot delivers a Messerschmitt Me 262A-1, the world's first operational jet-powered fighter aircraft, to the Americans, the first to fall into Allied hands.
• The Messerschmitt Me 262 Schwalbe (English: "Swallow") of Nazi Germanywas the world's first operational jet-powered fighter aircraft.  Design work started before World War II began, but engine problems and top-level interference prevented the aircraft from attaining operational status with theLuftwaffe until mid-1944. Compared with Allied fighters of its day, including the British jet-powered Gloster Meteor, it was much faster and better armed. One of the most advanced aviation designs in operational use during World War II, the Me 262 was used in a variety of roles, including light bomber,reconnaissance and even experimental night fighter versions.
  Me 262 pilots claimed a total of 542 Allied kills (although higher claims are sometimes made). The Allies countered its potential effectiveness in the air by attacking the aircraft on the ground and while taking off or landing. Engine reliability problems — from the pioneering nature of its Junkers Jumo 004 axial-flow turbojet engines, the first ones ever placed in mass production — and attacks by Allied forces on fuel supplies during the deteriorating late-war situation also reduced the effectiveness of the aircraft as a fighting force. In the end, the Me 262 had a negligible impact on the course of the war as a result of its late introduction and the consequently small numbers that were deployed in operational service.
