Patrolling the Ether

FCC has a video of this film and with the studio's permission uses it for training - hence I saw it. It was part of a series of WWII propaganda films on how obscure agencies were contributing to the war effort. There is some truth to the wartime role of the FCC in listening for axis spies who used radio and having armed agents look for them. This mission left FCC after the war. The details of the film are highly fictionalized and the acting reminds one of Reefer Madness.

J. Edgar Hoover was reportedly annoyed about the film saying it gave the FCC too much credit.

If you are interested in radio technology or FCC this is a good movie to watch with a beer in hand. It is historically significant in that it was the first film shown on TV before theatrical release - but at that time TV was an experiment and viewership was minimal.
