Flying Wings - The Horten H.VII
By Willie Bodenstein
The Horten H.VII flying wing fighter-trainer aircraft designed by the brothers Walter and Reimar Horten and manufactured by Peschke in Germany had its first flight in May 1944.
The H.VII design began as a test-bed for the Schmitt-Argus pulse-jet engine but this project was cancelled and the aircraft's role became that of a trainer. Walter Horten piloted its first flight and took part in many hours of a series of test flights, partly intended to quell concerns about the tailless aircraft's controllability in the case of an asymmetric power loss.
A number of prototypes were built and the H.VII V-3, nearing completion by the time that the allied advance reached the Peschke factory in Minden, would have been the first of twenty-production aircraft. Two H.VIIs were destroyed in the advance and one taken to the USSR.
