At one point some bats escaped, roosted under a fuel tank, set fire to the testing facility and burned down a hangar as well as the overseeing General's car.

The bats needed to be put into hibernation to get them into the bombs, but sometimes they weren't awake enough before being dropped, so the bats would plough into the ground still frozen.

The project was cancelled just after the invention of the atom bomb, on the grounds that it might do a bit more damage than a few bats. Dr Adams, the dentist who came up with the bat idea, still thought his was better. Don't disagree.
