Apart from the US ones, I already see Soviet training films for aircraft, but never from the other main Allied and Axis countries. Did they also employed audio-visual productions?
I saw one Luftwaffe one for the Me 262. I'm sure it's on U-Tube. I remember it show the fuel truck pulling up in front of the nose of the plane, and one of the "blackmen" motioning for the driver to get the truck out of the way of the 30 mm cannon! Good advise.
