We should invent a bomb that would sail down and then, before hitting the ground would open up with 40 to 50 bats stashed inside. They would all have plastic explosives strapped to their legs. Then the bats would disperse throughout the city going to hopefully, 40 or 50 different buildings. Then after a few minutes the guys back on the plane would push a button and destroy all of those buildings.



Some bats would have had a harder time dispensing of their bombs...

The bat-bomb was intended for Japan very flammable structure. With incendiary devices, not plastic explosive.

My favorite was BF Skinner's pigeon bombs. He trained pigeons to recognize ships, and keep them centered in a window by pecking at controls.

The pigeon was intended to be strapped into the special bomb. Not sure if they ever tried them in combat.
