Hitler was angry when Heydrich was killed. Hitler, who had a notorious sixth sense about assassination attempts, hated that Heydrich didn't take care of his security the way he should've and was very angry at him for getting murdered.
Hitler also personally ordered that Heydrich, who loved to fly, stop flying in Luftwaffe missions.
Heydrich’s next opportunity for aerial combat came during the Russian offensive. He flew numerous times over enemy territory and was engaged in several dogfights behind the lines. It was during one of these flights that he was forced to crash-land behind the Soviet lines, in the vicinity of Berezina. Eventually he was rescued by a German combat patrol. Lina Heydrich describes this incident as follows : “..Reinhard comes home, dirty, unshaven and very upset...He landed behind enemy lines, had hidden for two days and two nights and made his way on foot back to German units”. (..) Heydrich was awarded the silver bar for combat missions and the Iron Cross First Class. Hitler noticed the new decorations and was horrified at the thought of his Security Chief being captured by the Russians. From then on, he was strictly forbidden to undertake such dangerous flights again. Luftwaffe Reserve Major Heydrich was grounded.’
Fixed it.
