Robbiee, you are not wrong. We can argue about VRS or overpitching till the cows come home, but the reason why this accident happened does not lie in those two single states.

Crab, I think we are missing a crucial information here. What was the wind speed? From the very blurry picture what could be a wind sock, I would estimate the windspeed around 10 to 15 kts. Could be worse. But did he fly at that speed? What did he see on his speed indicator? Did he look at it? When he flared higher up, did he feel the loss of ETL?
If the windspeed was higher by a certain amount than the speed of the helicopter, then there is no VRS. I think I see the ship turning a bit and if that was the case, he would have a slight side wind. In that case again VSR would be very unlikely. Those vortices are not so stable and are easily blown away. We also do not know how heavy the ship was. There is the possibility that with that side wind and high gross, there wasn't just enough power left to stop the descend.
These are all things we do not know and who could change the picture radically.
