A Delta Air Lines (DAL.N), opens new tab regional jet flipped upside down upon landing at Canada’s Toronto Pearson Airport on Monday amid windy weather following a snowstorm, injuring 18 of the 80 people on board, officials said.

Three people on the flight that originated at Minneapolis-St. Paul International Airport suffered critical injuries, among them a child, authorities added.

U.S. carrier Delta said a CRJ900 aircraft operated by its Endeavor Air subsidiary was involved in a single-aircraft accident with 76 passengers and four crew members on board. The 16-year-old CRJ900, made by Canada’s Bombardier (BBDb.TO), opens new tab and powered by GE Aerospace (GE.N), opens new tab engines, can seat up to 90 people.

Canadian authorities said they would investigate the cause of the crash, which was not yet known.

Passenger John Nelson posted a video of the aftermath on Facebook, showing a fire engine spraying water on the plane that was lying belly-up on the snow-covered tarmac.

He later told CNN there was no indication of anything unusual before landing.

Pearson Airport said earlier on Monday it was dealing with high winds and frigid temperatures as airlines attempted to catch up with missed flights after a weekend snowstorm dumped more than 22 cm (8.6 inches) of snow at the airport.

The Delta plane touched down in Toronto at 2:13 p.m. (1913 GMT) after an 86-minute flight and came to rest near the intersection of runway 23 and runway 15, according to flight tracking website FlightRadar24.

Deborah Flint, president of the Toronto airport, attributed to the absence of fatalities in part to the work of first responders at the airport.

Michael J. McCormick, associate professor of air traffic management at Embry-Riddle Aeronautical University, said the upside-down position made the crash fairly unique.
