Yikes! I think G was right - he touched down kinda hard in a tail low
attitude and pranged the tail rotor. What I don't understand was why he
got airborne again when he shoulda dumped the collective and planted
it. The first guy that got thrown out was right in the path of the main
rotor when the helo rolled on its side it looked like..

Same, looks like he tagged the tail rotor and broke the shear
coupling, loosing TR authority.

Shoulda planted the collective right then, but I was not there, so I
am not to criticize.. ...

Dono if the 1st guy made it away or not, he was running when the
camera last saw him..

Here's my admitedly uneducated guess.

If the tail rotor hits the ground and breaks "stuff", then
the engine suddenly has an excess of power due to the lack
of drag because it's no longer driving the tail. That surge
of power then causes the main rotor to speed up causing
extra lift.
