Heydrich in Luftwaffe?
Less known side of Reinhard Heydrich - a front-line fighter pilot. He flew many (at least 60) front-line missions over Norway and later Russia. On 22nd July 1941 he got shot down by anti-aircraft artillery and crash landed in no-man's land and was saved by a German reconnaissance patrol in the area. His boss Himmler was furious (Heydrich violated direct order from him not to fly). After this adventure Heydrich never flew a combat mission again.
