Is anyone experimenting with human powered flight based on flapping
wing aerodynamics (hovering wing motion rather than soaring)?


I think Iccarus and Dadealus tried it. Leonardo Devinci drew pictures of
his ornithopter. If you watch the start of "Those Magnificent Men in
Their Flying Machines you will see short clips of ornithopters. They
didn't work.

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.
