It needs a PM to explain it?

Love to hear the story as it is rather unique behaviour.

How bad can it be?

Any update on this one?
Surprised that no video or revealing pics have surfaced yet.

Thanks for the link. Sobering report. Been >30 years since I flew a Jet Ranger. I am trying to sort out whether or not the investigators felt that the gusty wind was the major contributor to the mast bump, or a maneuver directly preceding it all going wrong ... probably need to read it again over a coffee and do some back of the napkin sketching of the described behavior of the helicopter as reported by the witness.
