Dornier Project 621
With Project 621 a of is Dornier at the beginning of 1960 planned year project referred that the development of an on Rogallo wings returning sounding rocket envisaged.
The project 621 missile was supposed to reach a top height of 80 km and from a height of 40 km it was supposed to return to the ground in a spiral, whereby all air traffic control regulations were to be complied with, so that the project 621 missile could even be used inland.
In May 1963 the concept was developed as the Dornier Do 122 by Dr. W. Kiessling presented at the European Spaceflight Symposium in Stuttgart.
