Rescued North Sea oil workers: 'Pilots were amazing'

Oil workers on board the helicopter which ditched in waters off Shetland have described the pilots who got them to safety as "amazing".

The 17 passengers and two crew are now onshore and all are safe and well.

The incident is the latest in a series of incidents involving helicopters in the North Sea and North Atlantic.

Offshore unions have said workers will need considerable assurance that flights are safe. An investigation is under way into the helicopter ditching.
