If you think Batman is awesome, you have to see where he gets his inspiration. Bats are the only mammals to have mastered the power of flight, and they learned to do it in much less time than birds. Their flying mechanism is radically different from birds as well. The difference stems from the structural difference in the wings of bat and a bird. While a bird's wings are like arms, the bat's wings are like a webbed hand. This difference allows bats to be more adept at flying in confined spaces, quickly change speed and direction mid-flight, and perform sharp maneuvers while in the air.
