Hello,
The following clip shows some footage of Strategic Air Command's (SAC) 1952 martial arts programm. Among others G. Funakoshi (1868–1957) with some of his students gave karate lessons as part of the programm. The clip contains two short karate sections:
0:08 – 0:09 M. Nakayama (1913–1987) demonstrating a side-kick
0:27 – 0:30 G. Funakoshi observing partner work
