This a a rather bad example of engineering. The size of the flies are not specified and under-power or overpower on one wing could doom the plane to fly in circles. Also, since flies are know to take of backwards, is there a more exact measurement as to how far their little butts should overhang the trailing edge?
I sincerely hope that younger or less sophisticated flyers will not take this design seriously. I would fear that some gung-ho experimenter might produce a scaled-up version using pigeons or sea gulls for power. And worse, there would always be some giant-scale enthusiast splitting a fence post and considering the use of turkey vultures for propulsion. Where would it all end? I wonder if there is a branch of PETA that works with flies?
