What about the actual bumblebee theory? neone believe, mind over matter?

I read in a science magazine that there was a logical explanation as to why it can fly. I can't quite remember what the answer was, but it had something to do with the way it flaps its wings. It's not up and down like on a bird, but backwards and forwards in some way... But I'm not sure. Either way, they were pretty vague on it, and I think that scientists still don't really know :D

For anyone that reads this later... http://en.wikipedia.org/wiki/Bumblebee:

"It is believed that the calculations which purported to show that bumblebees cannot fly are based upon a simplified linear treatment of oscillating aerofoils. The method assumes small amplitude oscillations without flow separation. This ignores the effect of dynamic stall, an airflow separation inducing a large vortex above the wing, which briefly produces several times the lift of the aerofoil in regular flight. More sophisticated aerodynamic analysis shows that the bumblebee can fly because its wings encounter dynamic stall in every oscillation cycle.

Additionally, John Maynard Smith a noted naturalist with a strong background in aeronautics, has pointed out that bumblebees would not be expected to sustain flight, as they would need to generate too much power given their tiny wing area. However, in aerodynamics experiments with other insects he found that viscosity at the scale of small insects meant that even their small wings can move a very large volume of air relative to the size, and this reduces the power required to sustain flight by an order of magnitude.

Another description of a bee's wing function is that the wings work similarly to helicopter blades, "reverse-pitch semirotary helicopter blades"."

I like this movie, but there is no science here.
