The Dornier Do 14 was a prototype seaplane, developed by Dornier Flugzeugwerke with backing from the Luftwaffe for experimental propulsion studies. The aircraft was similar to the Dornier Do 12.[1] Only one Dornier Do 14 was constructed for testing, the aircraft registered as "D-AGON",[2] after test flights during 1936, the aircraft engines were subsequently dismantled in 1937.[3] The prototype aircraft was finally scrapped in 1939.[2]
