In WW2 pilots carried metal spheres in case they ditched in the ocean

During World War II, American pilots were given hollow metal spheres to be used when their planes went down over water. Metal, as you probably know, tends to be quite heavy and quite useless as a flotation device.

So why were these pilots given chunks of metal? Well, they were told that if they dropped the sphere into the ocean, their current position could be worked out by allies in the region, and they would be rescued.

However, as foreign intelligence was soon to find out, the spheres were just that - hollow metal spheres - no electronics, no radio equipment, no imbued magical properties. So was the military just playing with itís pilots, or was there actually something to these spheres?

Well, some of the details are still kinda top secret, but with a little physics and an active imagination, itís possible to work out how they were used. Iíll try to summarize things without delving to deep into the physics.
