context: The highest officials of the US command knew very well how valuable the loot fell into their hands: the name of von Braun headed the Black List, the code name for the list of German scientists and engineers from among those whom American military experts would like to interrogate as soon as possible. On July 19, 1945, two days before the planned transfer of the territory to the Soviet occupation zone, American Army Major Robert B. Staver, Jet Propulsion Chief of the Research and Intelligence Service of the US Army Artillery Corps in London and Lieutenant Colonel R. L. Williams landed von Braun and the heads of his departments in a jeep and delivered from Garmisch to Munich. Then the group was transported by air to Nordhausen, and the next day - 60 km southwest to the town of Witzenhausen, which was in the American zone of occupation [33]. Von Braun stayed briefly at the Dastbin interrogation center (English: Dustbin, The Garbage Box), where representatives of the Third Reich's elite in the field of economics, science and technology were interrogated by British and American intelligence services [34]. Initially, he was recruited to work in the United States under Operation Operation Hopelessness (English: Operation Overcast), which later became known as Operation Paperclip.
