See a bee fly

Ever wondered how a bee manages to fly -- see here, but it's a BIG file (5mg).

First of all physicists said bees couldn't fly. Then they found out about lift through vortices flowing along the wings as they flapped. Now they've found that the wings roll and flap back into their own wake -- creating higher forces than flapping in still air. And then there is “added-mass force” which I'm afraid I don't understand at all -- but you can read all about it here.
