After the war, the Whizzers added Luftwaffe test pilots to the team, one being Hauptmann Heinz Braur. On 8 May 1945, Braur flew 70 women, children and wounded troops to Munich-Riem airport. After he landed, Braur was approached by one of Watson's men, who gave him the choice of either going to a prison camp or flying with the Whizzers; Braur thought flying preferable. Three Messerschmitt employees also joined the Whizzers: Karl Baur, the Chief Test Pilot of Experimental Aircraft, test pilot Ludwig Hoffman, and engineering superintendent Gerhard Coulis. Test pilot Herman Kersting joined later.
