Ashley Zook, a passenger on the flight, uploaded a Snapchat video of herself still strapped into her seat inside the flipped plane, with the caption: “My plane crashed. I’m upside down.”

In the video, she can be heard exclaiming: “What the f**k.”

Later, she shared another video from outside the aircraft, showing the plane resting upside down on the ground with other passengers nearby.

“I was just in a plane crash. Oh my God,” she says in footage shared by CBC.

Another passenger, John Nelson, also posted on social media, sharing a video on Facebook in which he explains that the plane “crashed” and is “upside down” while officials work at the scene.

“Most people are going to be OK, we’re all getting off, there’s some smoke going on,” he narrates.

The Transportation Safety Board of Canada has launched an investigation into the crash.

The Federal Aviation Administration (FAA) released a statement saying: “The NTSB is leading a team of U.S. investigators to assist the Transportation Safety Board of Canada with their investigation of today’s accident of a Delta Air Lines Bombardier CRJ900 at Toronto Pearson International Airport.

“Per international protocols under the International Civil Aviation Organization’s Annex 13, any information about the investigation will be released by the Transportation Safety Board of Canada.”
