Passengers were forced to call 911 when their flight was grounded at the Ottowa, Canada airport for six hours Monday night without air conditioning, causing at least one child to get sick.
Air Transat Flight 157 from Brussels was scheduled to land in Montreal at 3:15pm, but couldn't because of severe storms.
After circling around Montreal for a few hours, the plane was diverted to Ottowa, where it landed around 5pm.
Passengers say they were given little information about why they were grounded in the ensuing hours, or how long they were going to be kept on the plane.
At first, the air conditioning was kept on, but as the plane's fuel supply dwindled, the pilot shut off the power - cutting off the air conditioning and lighting.
