The Sea King Mk 50, side no. '02' was from 817 Squadron RAN with 4 crew on board as well as pax. It crashed during approach to land at Aman Draya village on the west coast of Nias Island.
Other details will be released in due course, as always speculation over the cause is too early, please don't fuel it!
There was no involvement by the Booty or any other ex UK aircrew. All condolences are much appreciated and will be passed on to the families. As expected it has hit hard and all are feeling it.
