FAKE! I was on a Jumbo Jet and filmed the engines - they didn't change at all. (Then the stewardess gave me a hard time for not turning off my mobile in flight)

So - are you telling me that when you take a photo with your phone it's NOT an instant 'hit' but more of a very quick top-to-bottom scan ???

Latest comment: Not fake Bob, it is called aliasing, the distortion that occurs when a continuous time signal has frequencies larger than half of the sampling rate. the propellers are spinning at frequencies higher than the cameras Nyquist sampling rate. Also probably some reflections add to the distortion
