He then says:
«The helicopter flew normal, then i saw it wobble and heard a «bang», after about two seconds i heard one more «bang» and then the helicopter goes straight to the ground»
This timeline must not be real due to the difference between the speed of sound and speed of light. Altitude was 2000ft, so a minimum difference of 2 seconds!
I assume first the bang, followed by the wobbling motion?
