Being tired behind the controls of an aircraft is the number one safety concern pilots say they face on the job. Next month, the federal government is expected to roll out new regulations to limit how long pilots can fly. But the country's largest pilot union says the proposed limits on flight times are still too long and are not supported by the science. Under the draft regulations, a pilot could fly for 10 and a half hours through the night before breaking the rules. Milt Isaacs, CEO of the Air Canada Pilots Association, said that's still too long to go without rest.
