Mechanical veined ornithopter in forward flight Video
From the paper by Hiroto Tanaka and Isao Shimoyama entitled "Forward flight of swallowtail butterfly with simple flapping motion," Bioinspiration & Biomimetics Volume 5, Number 2 Paper 026003, 2010. http://dx.doi.org/10.1088/1748-3182/5/2/026003
Abstract: Unlike other flying insects, the wing motion of swallowtail butterflies is basically limited to flapping because their fore wings partly overlap their hind wings, structurally restricting the feathering needed for active control of aerodynamic force. Hence, it can be hypothesized that the flight of swallowtail butterflies is realized with simple flapping, requiring little feedback control of the feathering angle. To verify this hypothesis, we fabricated an artificial butterfly mimicking the wing motion and wing shape of a swallowtail butterfly and analyzed its flights using images taken with a high-speed video camera. The results demonstrated that stable forward flight could be realized without active feathering or feedback control of the wing motion. During the flights, the artificial butterfly's body moved up and down passively in synchronization with the flapping, and the artificial butterfly followed an undulating flight trajectory like an actual swallowtail butterfly. Without feedback control of the wing motion, the body movement is directly affected by change of aerodynamic force due to the wing deformation; the degree of deformation was determined by the wing venation. Unlike a veinless wing, a mimic wing with veins generated a much higher lift coefficient during the flapping flight than in a steady flow due to the large body motion.

It doesn't appear to be flying so much as flapping while falling.?

We've already created a synthetic cell, it's living and was created? from, basically, scratch.
Where's your god now?
"Define? flight" ...
"Define? flight" comes to mind as this looks more like slowed falling than 'flight'.
@11file He created ...
@11file He created the heavens and the earth. He built the Earth, so therefore he could not have been born here. Which makes him an extra-terrestrial. Your god is an alien and yet you refuse to look at the bible from an? alien point of view. Which makes you a hypocrite, so shut up, quit trying to push you religion on other people and just enjoy the god damn video. Nice vid BTW. I wouldn't mind making one of those.
