Bumblebees CAN fly! The oft heard ridicule of scientists that say a bumble cannot fly because its wings are too small, in spite of the evidence of their own eyes, is based on a misrepresentation of an incident that occurred in the 1930s. McMasters (in the Amer. Sci. 77:164-169) reports that a noted Swiss professor of aerodynamics at a dinner party with biologists was asked about the aerodynamics of wasp and bee wings. He performed some calculation for the bumblebee based on a smooth wing and got a low Reynolds number "proving" the bee incapable of flight. He obviously knew that the calculations were simplistic, and later (after examining a wing under a microscope and noting the bent and folded nature of the wing), corrected his error, but like the news media of today, the correction received little notice.
