: One reason this does not work is because humans do not have the strength
: to weight ratio for muscle powered flight. Birds are specialized. Even
: their skeleton is porous so the bones are lighter.

The human-powered planes that have crossed the English channel
required something like 2.5 HP (about 2000 Watts). That's about the most
efficient plane you can make that'll carry a person. Try peddling like
2.5 horses for more than a few minutes and see if you'd like to "land" yet
