Weaver wrote:Humans certainly modeled airplane wings after birds' wings - there was a whole lot of study of the shape and motion of bird wings in early flight attempts.

I note that there very few sparrows in the desert - must be why it doesn't rain there much.

Modern fighter aircraft, like the Swedish JAS-39, don't have internal stability, meaning, their maneuvrability is enhanced.

Sad, sad, sad.
SO my proposition is we either stick to discussing the aerodynamical stability of pterodactyls, or, possibly, go to the pub, hard as that may appear, what with us spread over 6 continents, but, where there's a will ...
