Two allegedly drunk Canadian pilots were arrested Monday at Glasgow Airport just before taking to the skies with hundreds of passengers in tow, Glasgow Live reports. According to CBC, the flight crew noticed there was something off about the pilots and went to authorities. "We saw five policemen get onto the plane and we thought, 'There's a problem,'" one passenger says. The 250 or so passengers on board the Scotland-to-Canada flight were told there were "operational reasons" for the delay, the BBC reports.
Pilots Jean-Francois Perreault, 39, and Imran Zafar Syed, 37, were arrested on suspicion of violating the Railway and Transportation Safety Act of 2003. If convicted of being drunk prior to a flight, they face up to two years in prison. The airline, Air Transat, apologized and provided vouchers to passengers, who had their flight delayed until Tuesday.
