Hi,
I just read the BFU report of the accident.
I agree with the translation of Flying Bull and Phil77.
I found nothing about an approach to land.
...a right turn with high bank towards the ship they did a tight left turn followed by a high speed descent towards the shelf ice border. short before the shelf ice border there was an sharp and abrupt pull up. At that point the mast moment warning light comes up....
....."the pullup in front of the ice followed by a push-over and a steep descent that had been terminated - here ended the memory of all eye witnesses..."
...there was an merry mood throughout the maneuver...
I fly the BO 105 myself and I know that kind of flying - very sad
