Hi gafa,
donīt have time to translate it in total.
Short version:
There have been witnesses and videoevidence from inside the helicopter.
Pilot did some steep turns, sharp decends and pull ups to the ship and to the shelf-ice-border.
Seemed to do a negative g manover pull up and putting nose down with decent afterwards and impacted shortly afterwars on a great snowarea with high speed, left skid first (was torn off).
Both occupants in the front died, passengers in the back were injured.
Donīt say anymore....
Greetings Flying Bull
