The Globe and Mail reports in its Tuesday edition that authorities are investigating the collision of an Air Canada Express plane and a fire truck that killed two pilots on a runway at New York's LaGuardia airport late Sunday night. The Globe's Eric Atkins and Maura Forrest write that an investigation by the U.S. National Transportation Safety Board, with assistance from Canada's Transportation Safety Board, is expected to examine why the emergency vehicle was cleared by air traffic control to cross the runway in the path of the landing passenger jet. The fire truck was reporting to a separate incident when it was struck on the runway by the CRJ 900 regional jet, operated by Air Canada contractor Jazz Aviation, which was carrying 72 passengers and four crew members. One of the pilots who died was Antoine Forest, 30, of Coteau-du-Lac, Que. The other pilot who died was Mackenzie Gunther. Thirty-nine passengers and crew and two firefighters were taken to hospital. The airport closed after the collision, but reopened Monday afternoon. Kathryn Garcia at the Port Authority of New York and New Jersey, said 32 of the 41 injured had been released from hospital, while nine remained in hospital with "serious injuries."
