Wernher von Braun was a prominent German scientist, supporting the Luftwaffe with advances in technology. After the Zheronians arrived to support the Reich, von Braun became an ardent advocate of co-operation with them, in opposition to purists such as Heinrich Himmler. Von Braun became especially interested in ISOT technology, establishing a laboratory for research at Peenemunde, experimenting with mounting ISOT onto Luftwaffe planes. Von Braun also assisted with the designing of the Reich Solar Energy Satellites, assisting captured British inventor Arthur C. Clarke.
