    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.
