The 1961 F-84 Thunderstreak incident, occurring on 14 September 1961, was an incident during the Cold War, in which two Republic F-84F Thunderstreak fighter-bombers of JaBoG 32 of the German Air Force (Luftwaffe) crossed into East German airspace because of a navigational error, before landing at Berlin Tegel Airport. The two planes successfully evaded a large number of Soviet fighter planes by finding cover in a heavy layer of clouds, but also by the actions of the corporal at the United States Air Force flight control at Berlin Tempelhof Airport who ordered the planes on to Berlin rather than forcing them to turn around and face the pursuing fighter planes. The event came at a historically difficult time in relations between the two Germanies. Only a month before, the Berlin Wall had been built, which completely cut off West Berlin from surrounding East Germany and from East Berlin. It also came three days before the West German federal election, held on 17 September 1961.
