RE: Air ambulance
He carefully pivoted the helicopter around his seat in the video. He should have pivoted around the rotor hub. I bet he thought he had perfectly kept the helicopter in one place. In his mind thinking that something had blown into the rotor instead of him moving into the wires. His seat should have been over the ditch after the pivot. I wonder how many pilots pivot the helicopter around their seat in routine ops. Instead of pivoting around the rotor mast. Must be hard to have a feel for 25' of fuselage behind you. Side to side and up and down is easy because visual clues of the aircraft's dimensions.
Isn't there a rule of thumb on old pilots and bold pilots.
