An Antigravity Helicopter?

Check out this clip:

 

What the photographer has done, if I understand it, is to sync his camera speed with the helicopter's blades.  The blades are in the same position each time the camera takes a shot.  That's the kind of magic I can believe in.

You will recall that in the old western movies something like that used to happen with the wagon wheels. Sometimes they'd seem to be spinning forward, sometimes backward, and occasionally just standing still. It also used to be difficult to get a picture of a TV screen with a video camera for much the same reason, matching scanning speeds. Finally, noise reduction systems work along the same lines.

I hadn't thought about the wagon wheels, but yes! The poet in me thinks that this trick of perception is very important.
