Passengers stuck on grounded plane in 'unbearable' heat call 911

Passengers on board an Air Transat flight from Brussels to Montreal were left stranded on the plane at Ottawa's Macdonald-Cartier International Airport for more than five hours after the plane was diverted, due, in part, to stormy weather.

As time wore on, passengers started sharing updates about their situation on social media.

They complained that the aircraft lost power and air conditioning, leading to 'unbearable' heat, according to Brice de Schietere, a Belgian diplomat who posted these videos on Twitter from inside the plane.

De Schietere noted that passengers began calling 911 after a number of hours when they were unable to leave the plane.

On Twitter, Air Transat said it was waiting for an authorization from the airport to allow passengers off the plane.

The airport, however, tweeted that it is 'up to the airline to determine whether to deplane or wait it out.'
