New footage has emerged from the Viking Sky rescue that took place on Saturday that shows passengers being airlifted to safety as huge waves toss the ship around. 

A camera mounted on a rescue worker's helmet captured the moment passengers were hoisted one by one from the cruise ship to a helicopter. The evacuations took place in extremely difficult conditions. Norwegian media reported gusts of up to 38 knots (43 mph) and waves over eight metres (26ft) in an area known for its rough, frigid waters. Twenty people were treated for injuries including broken bones, cuts and bruises, rescuers said.
