Hans Klein died on 18 november 1944, he was a deputy Commander of all fighters in the Luftwaffe. He finaly attained the rank of Major-General. He wasn't really behind the NSDAP. Nazis saying he had died in a car crash. His family didn't believe it but the Nazis wouldn't let them see his body. One of his family member sneaked in and saw his body...He really died from a bullet to the back of the head, not a car crash !
