Towards the very end of World War I, the company Hanseatische Flugzeugwerke (Caspar-Werke AG) constructed a fighter aircraft designated as the Caspar D.I. The development of this project is attributed by some sources to the company’s head, Karl Caspar, and by others to Ernst Heinkel.
Design and Specifications
The Caspar D.I was a single-seat, single-strut biplane, powered by two Oberursel U.I engines, each delivering 100 hp. Unfortunately, the fighter could not be tested before the war concluded, preventing its combat deployment.
Project’s Ultimate Fate
In 1919, an attempt was made to convert the aircraft into a civilian plane. However, during ground tests, an accident occurred due to engine failure. This unfortunate incident led to the project’s definitive cancellation.
