How can Bees Fly?

Question: How can Bees Fly?
Can you please explain exactly how bees are able to fly?
---------------------------------------
Well, the first question is what the "theory" referred to is.
I would guess this is based on standard airplane construction, that if you
built an airplane with wings like a bees that was as heavy as a bee and was run by
some engine (propeller or jet) that was as powerful as a bee, it would not
get off the ground.  The solution is that a bee does not run like an airplane -
its wings are not fixed, for one, and like all flying animals, it does not
power itself with a jet or propeller, but by the actual flapping of its
wings.
The result is probably some very complex air currents - I assume they can be
modeled these days, and maybe somebody has done it, but in any case the
flight of a bee cannot be described by any simple theory.

They fly because they flap their wings.  The flapping motion
imparts downward momentum to the air, and as a result, the bee stays aloft.

The wings do not just move up and down.  The tip of the wing also moves
forward and backward and the end of the wing moves in an oval shape.  In
addition the wings tilt during each flap.

All of this complicated "paddling" allows it to fly.    It is not really
known "exactly" how the bee flies.

The direction the wings move was not known until high speed photography was
invented.  Even then, to get a GOOD understanding of air flow requires that
some tracer be put in the air (like smoke) so that the researchers can find
out how the wings are pushing the air around.

If a bee hovers over your hand, you can feel a gentle breeze from the little
wings.
