A bird is a wonder of flight. Man had to unravel the
mysteries of flight. He had to first understand the forces on earth that
enable flight, and then to try and duplicate a bird's actions. It wasn't
until technology enabled him to develop an internal combustion engine
that he overcame the difficulty of minimum weight and maximum power,
something nature conquered long ago. Also, the invention of the slow
motion camera enabled man to capture the split second motion of a bird's
wing in flight. He could now see what had been impossible to see before,
and could master controlled flight.
