[Junkers]

The Payen never flew in German service or as test aircraft. It was stationed in the south of France while the incident with the unknown delta-plane was at the Normandy coast in northern France.

The Gyropter had most probably flight characteristics similar to a helicopter therefore the witness is not wrong when stating that the vehicle flew very slowly.

Wibault´s delta airplane had rotor arms in the middle of of the fuselage and at the ends small jets or jet-outlets like some small post-war helicopters ejecting hot exhaust gases or simply hot air. So this princlible was already used in Wibault´s delta craft which had an additional jet-engine at the rear, small tube, which enabled the vehicle to accelerate and dash away.
