Japan’s Secret WWII Weapon: Exploding Balloons
WWII saw the development of some zany designs for weapons, such as when the U.S. developed pigeon guided missiles and (literal) bat bombs (the latter of which were a little too effective, accidentally destroying the testing base when they escaped), or when the Soviets trained exploding anti-tank dogs. Not to be left out of the fun, the Japanese developed their own oddball weapon. Starting in November of 1944, Japan launched over 9,000 devices they called "Fu-Gos" aimed at the United States and Canada. Fu-Gos were hydrogen balloons equipped with incendiary devices that, in theory, would be transported over the Pacific Ocean via the jet stream to devastate the landscape, perhaps starting massive fires in farm fields and forests across North America.
