The bodies of three of the four oil workers who died when a helicopter plunged into the North Sea have been brought back to the mainland.
A passenger ferry carrying the bodies arrived at Aberdeen Harbour at 7am this morning.
It is understood that the fourth body will arrive tomorrow.
The Super Puma was carrying 16 passengers and two crew from the Borgsten Dolphin platform when it crashed into the sea off Shetland on Friday evening, killing three men and one woman.
It is not yet known what caused the CHC-operated helicopter to crash into the sea.
Tributes have been paid to the victims, named as Duncan Munro, 46, from Bishop Auckland, County Durham; George Allison, 57, from Winchester, Hampshire; Sarah Darnley, 45, from Elgin in the Highlands; and 59-year-old Gary McCrossan, from Inverness.
Experts believe more people could have died, after a helicopter ditched into the North Sea killing four people, but added that the "skill of the pilots" played a part in saving lives, according to the British Airline Pilots Association.
Speaking to The Daily Telegraph, a spokesman said: "It is too early to say exactly what happened, but ditching a helicopter on water is extremely difficult.
"The skill of the pilots in dealing with what looks to have been a catastrophic power failure at low altitude almost certainly ensured that more people didn't lose their lives."
Investigators will try to establish what caused a helicopter to plunge into the North Sea, killing four oil workers, after the wreckage was recovered from the water.
Misty conditions last night hampered efforts to salvage the wreckage of the Super Puma and transport it back to shore for examination by a team from the Air Accidents Investigation Branch (AAIB).
It is understood that the remains of the Super Puma AS332 L2 were eventually lifted on to the deck of the vessel Bibby Polaris which was due to travel to a mainland port.
It is hoped information on the helicopter's black box recorder will help establish the cause of the crash.
An emergency meeting of gas and oil companies will be held tomorrow in the wake of
Friday's deadly helicopter crash off the coast of Shetland, which killed four oil workers.
The entire UK fleet of the commercial Super Puma aircraft has been grounded following the tragedy amid a growing backlash against the aircraft.
