Canadian military investigators say a malfunctioning seat led to the loss of one of its search and rescue helicopters last month. The crew of the CH149 Cormorant was doing hover training above the runway at Gander International Airport in Newfoundland and Labrador when the mishap occurred. There were six crew on board and five were injured, two seriously. The aircraft ended up on its side and the tail broke off. All the rotors sheared off.
