There is an aching gap between the reality of the comparative risks to aerial camera crew and how it is percieved by media managers and even the helicopter industry itself.
Nailed that one.Especially junior pilot hour sharks out there to do what they think is an easy job.
I think I notice in the last video how there is a sudden jerk to the left in the camera frame immediately prior to the rapidly increasing right rotation.
That might indicate the Tail area running into something which impeded it's movement just prior to the rotation.
There is nothing unusual about the rotation to the right in a "normal" helicopter whose M/R turns in the correct sense, (ahem) and certainly nothing unusual about the severity of rotation when a T/R drive fails.
Been there done that, leaves yer false teeth and glasses and head behind while yer body has gone over there. The only remedy at that height - snap the throttle closed and right now sah.
