Robert Cribb, Fred Vallance-Jones and Tamsin McMahon of The Toronto Star analyzed the aviation data and found that "more than 80,000 passengers have been put at risk over the last five years when airplanes they were travelling in came dangerously close together in Canadian skies." Between 2001 and mid-2005, there were more than 800 incidents in which planes got too close to each other. "The investigation found a safety system straining at the seams. Experts — pilots, mechanics, airline workers and people who study aviation data — warn significant changes must be made to prevent a major catastrophe."
