1) Backpack is clearly attached with better-than-normal strapping in front. Watch preflight carefully. EDIT: Look here (http://www.humanbirdwings.net/wp-content/uploads/2012/03/IMG...)

2) If it's a kite and gets off the ground, so what? Worked, didn't it? Also, for wings, it just has to be glider plus produce enough thrust off the flapping to keep it aloft, yeah? We're not making an airplane here. EDIT: Looks like there is an internal core wing structure (http://www.humanbirdwings.net/wp-content/gallery/fixingwings...) with the extra fabric functioning somewhat like secondary feathers.

3) Motors alone aren't made for rapid oscillation--that's why we have other mechanical devices such as cams, pistons, etc. If you listen carefully at liftoff you can hear a highpitched whine, perhaps a small IC engine. EDIT: Confirmed as electric motors using battery packs.

4) You probably just need to change the angle of attack, and maybe dick around with Cg and Cp. So, until I see your numbers, I'm not discounting this out of hand.

5) Where in the press release does it say he uses an Android OS? It says he uses accelerometers from an HTC smartphone, sure, but I didn't see anything about running Android. EDIT: Taking my own advice, look here for system diagram: (http://www.humanbirdwings.net/wp-content/uploads/2012/03/exp...). He uses one phone per wing, plus additional computation power.

6) So what? That alone isn't implausible.

7) That's probably because this is worth good money in patents. EDIT: Check the website here (http://www.humanbirdwings.net/press/).

Why is it so absurd that this might work?
