An eyewitness has described the moment a helicopter fell "like a torpedo" into the North Sea, claiming 16 lives, including that of a man from Norwich.
The account was given on the first day of a fatal accident inquiry (FAI) almost five years after the Super Puma plunged into water off Aberdeenshire
Lidvar Olav Hildre, a ship's mechanic, was painting a railing on board the Normand Aurora, a platform supply boat sailing to Norway.
He heard a helicopter making a "normal buzzing noise" above the ship.
"Apart from the helicopter noise I didn't hear anything else - then suddenly there was silence," he said in a statement to police which was read out at the inquiry in Aberdeen.
"This made me look into the air, as this was unusual, and I saw on the starboard side of us an oblong shape falling like a torpedo towards the sea."
