LISTEN: Will Super Pumas ever fly in the North Sea again?

Investigators looking into the helicopter crash off Norway in April have found metal fatigue in the main gearbox - and there's currently no effective way to detect a similar failure in advance. Thirteen people - including Iain Stuart from Laurencekirk - were killed when the rotor came off the aircraft at 2000 feet. The North Sea fleet of Super Puma 225s is currently grounded. But Audrey Wood, whose son Stuart was killed in a similar accident in 2009, thinks this proves they should be taken out of action for good.
