What if we have wings, is there a need a plane to fly?
Birds, bats, and insects may rule the skies, but as any skydiver knows, you don't need wings to fly. They're controlling the aerodynamic forces; they can initiate spins, rolls, tumbles, and really control their body posture to great accuracy in midair.
We can walk but we still have to use cars. I think if birds with a very light endoskeleton get tired imagine humans. It would sure be fun to take a S*** on some pigeons though just for the revenge.
