What the Fuck Is an Airplane?

The German general staff had some shitty old cars because remember, even having a car back then kind of sucked. And also this is the era when like absence would make you trip. So General Samson off, commander of the second army, use the easiest thing he had for communication, which was radios. When they worked, they were completely unencrypted because nobody encrypted anything yet. They were broadcast in the open in plain Russian. That meant any German listening nearby could simply tap in and like, oh, yeah, I can hear the Russian radio communications.
