Airborne Magnetometer. Turns out the bird really is the word. The “bird” refers to an airborne magnetometer, so nicknamed by the U.S. Geological Survey, which made this 1952 film. This device is towed by a plane and measures magnetic anomalies in the earth’s surface, which may indicate mineral deposits. And we all know what mineral deposits mean, don’t we? Mining of all kinds of valuable minerals, that’s what. The film is rather dry, since narration is the only thing on the soundtrack, but it does have lots of great visuals of various forms of clunky 50s technology, which I happen to be fond of. And it also lends itself well to msting, especially when you consider that one of the assigned crew is known as “The Observer”. This would also be a good film to mine for a video project.Ratings: Camp/Humor Value: ***. Weirdness: ***. Historical Interest: *****. Overall Rating: ***.
