It was here that Nazi interrogators had questioned every Allied pilot who had been shot down during the war. The Luftwaffe’s lead interrogator, Hanns Scharff, kept a diary. “Every enemy aviator who is captured… will be brought to this place for questioning. It makes no difference whether he is taken prisoner at the front lines or whether he comes dangling down from the sky in the most remote location… he comes to Oberursel,” wrote Scharff.
