In the year 1943 the german Luftwaffe gave order to the aircraft companies to build a propeller driven plane that could reach high speeds on sea level, to counter the allied fighters. It also should be able to play the interceptor role over the german skies against the threat of english and american bombers.
The Junkers company was trying to success in the competition with the "Spatz" ( eng. Sparrow ). The Reichsluftfahrtministerium ( Ministry of aviation ) ordered three of these planes, and different pilots should test them in any scenario of the modern dogfight, interception and ground attacking. The plane proved to be a scary enemy to the allied air forces.
