I dont fly helo's, only planes but I think they were testing "ground resonance" or something like that. Basically if conditions are right the aircraft will tear itself apart. Maybe the rotorheads on the board can help explain. But no it wasnt just tied down and the pilot was trying to take off!

Looks like some kind of maintenance high power turn that soiled somebodies drawers big time. If you listen real carefully you can hear somebody yell, oh shit, about the time it starts shaking and shutting down.

I've seen that video several times on different sites. Not sure if it's a test, or demonstration, but it's ground resonance.

I've seen this before too, but I don't remember the exact details. It's definitely a test fixture though. Dr_Nimslow is probably right in that it's a ground resonance issue.
