One time I accidently parked in the managing partner's spot at the CPA firm I worked at. A supervisor noticed and said, "Whoa! CLM!. I then learned that CLM stands for Career Limiting Move. I'll bet Reinberger was thinking the German equivalent of "CLM!," when he found that he had survived the crash landing.
Lol. I think you are right. Apparently Reinberger, during interrogation, had grabbed the papers again that were sitting on the table and threw them in the fire. They were quickly retrieved. Then he went for the interrogator’s gun supposedly with the intent of shooting himself. He might have just as well parked in Hitler’s spot.
