Plane Detector Like Giant Spoon (Jan, 1932)

Plane Detector Like Giant Spoon

WHEN Stockholm, Sweden, was recently “bombarded” from the air in a sham attack, a new and strange type of sound detector was used to pick up the planes. Three giant spoon-like ears caught the sounds in their concave surfaces, rendering the device sensitive to motor hums at a surprising distance.

    Looks to me like what would happen if the Snap, Crackle, and Pop guys went to work for the Keebler Elves.

    Maybe it works better, but the War Tubas look so Dr. Seussian.

    Were this reversed, to sonically shoot planes down, that would be cooler.
