More eyes in the sky, but a cool idea...

That toy helicopter they sell on tv has that same set of propellers -- but it only weighs much less than an ounce, total -- I think.

There's no way the thing in that photo (spy camera) could possibly fly. It would have to be a much bigger (+ noisier) machine to carry a camera, etc.

Not possible to have a flying machine, with camera, etc. that looks like that photo.
