Perhaps sitting on the left he wasn't expecting the ground so soon, believing that it was at the height of the ground slightly to the left of his path where he eventually finished, which is probably where his eye was?
Asking AnFI about what makes him "think" is a lost cause.
He does not.....as evidenced by his post and suggestion the choice of Pilot Seats could be the cause of the helicopter's amazing slalom path down the mountain side.
Sadly....it was a single engine machine thus we are spared AnFI's usual rubbish about Singles v/ Twins.
