Just subsequent to this clip an Ichthyosaur being ridden by a man with glasses and a trimmed beard fly over and lands on the helicopter, after which it explodes, a victim of the Ichthyosaurs ravenous appetite.
I wonder if the pilot did this on purpose... a good enough helicopter pilot can use throttle and cyclic to keep revs in a certain range and still maneuver.
I'm guessing the frame rate of the camera is what causes this, or is it being propelled by the jets? Judging from the audio, I hear some motherfucking rotors. SOMEBODY BE TRICKING ME.
