Among the vast array of exhibits one can find an original Jumo 004A, one of the first jet engines in history, as well as a Focke-Wulf Fw 190, a Messerschmitt Bf 109 and a Supermarine Spitfire.

The entrepreneur Günter Leonhardt was already interested in gliding as a teenager and volunteered for the Luftwaffe.

For this he rescued several Ju 52 from a Norwegian lake in the Arctic Circle, which had sunk there in 1940.

In 1992, he partially transferred his collection to the Aviation Museum Laatzen-Hannover, located on the premises of the company he by then owned.

In addition to the aircraft collection are numerous items of everyday use, such as vehicles and clothing.
