RIP, and I agree the guy in the orange deserves a medal.
That tail rotor landed more than a hundred feet away from the rest of the helicopter.
If the tail-rotor (and possibly the tail rotor gearbox) actually separate from the aircraft in flight, can the R44 sustain that from a C of G standpoint? I know that proved terminal for a Jet Ranger in scotland some years ago.
Also, in forward flight, I wonder if that made entering an autorotation problematic or even impossible because of the resulting nose-down pitching moment?!
