Bomber bat! 

Learned some wierd history about an experiment that took place in World War II when scientist tried to turn bats into viable incendiary bombs. It was a failed attempt of course, because bats couldn't be trained same as pigeons. The bats' intented target were the Japanese, but pretty much it was the scientists base that got bombed in the end. It's funny how this crack-pot plan got approved even the begin with.

These were drawn for a tattoo course I took a part in. The design is available as a sticker at Redbubble.
