During the early years of its existence, the NSFK conducted military aviation training in gliders and private airplanes. When Nazi Germany formed the Luftwaffe, many NSFK members transferred. As all such prior NSFK members were also Nazi Party members; this gave the new Luftwaffe a strong Nazi ideological base in contrast to the other branches of the German military, who were composed of "Old Guard" officers from the German aristocracy. They were also used to transport Jews and homosexuals into concentration camps.
