Monstrous Mike, I'm no scientist, but I do have several Biology textbooks (for example: Biology, Campbell and Reece, 3rd edition, Benjamin / Cummings Publishing Co.) from the late 90's (a very common 1st and 2nd year textbook in most US universities). At that time there was still no conclusive explanation explaining how the geometry, displacement, and mass of bee's body can allow for it to fly.
All it said was that scientist "assume it has something to do with the movement of the bees wings". Duh!
It goes on to say the US military is even studying it (as of that date) and hope to be able to incorporate some of natures wonders in future designs.
Assuming these folks aren't liars, I wouldn't call this an urban legend. So they've disproved one theory that claimed a bee "couldn't fly". They haven't not adequately explained the physics and reasons as to why a bee "does fly".
A difference you can surely accept.
