During 1936, von Braun's rocketry team working at Kummersdorf investigated installing liquid-fuelled rockets in aircraft. Ernst Heinkel enthusiastically supported their efforts, supplying a He-72 and later two He-112s for the experiments. Later in 1936, Erich Warsitz was seconded by the RLM to von Braun and Heinkel, because he had been recognized as one of the most experienced test pilots of the time, and because he also had an extraordinary fund of technical knowledge. After he familiarized Warsitz with a test-stand run, showing him the corresponding apparatus in the aircraft, he asked: "Are you with us and will you test the rocket in the air? Then, Warsitz, you will be a famous man. And later we will fly to the Moon – with you at the helm!"
