How are we be being conned? Or did they finally invented anti gravity?

That was quick. It's just a matter of exactly the right frame frequency and a very short shutter speed. Of course it helps that helicopter blades move at a constant angular velocity.

I love this video, it brings out every half-wit to post conspiracy theories on the comments of youtube.

Looks like a good idea - having those blades spinning around must be dangerous!

Never realised the speed was that precisely controlled though.

Obviously this is a plot by the Russians to destroy America. Mother bear Russia is getting exactly what it wants by you looking at this video!!
