The lawsuit claims the crash, which involved Flight 4819 skidding down the runway upside down after toppling over, was caused by the flight crew’s “gross negligence and recklessness.”

Delta Air Lines has shared some information about the crew who piloted a Minneapolis-to-Toronto flight that crashed while landing on Monday. The airline said it released the information in response to social media posts “containing false and misleading assertions.

At least 18 people were injured when a Delta Air Lines flight from Minneapolis crashed upon landing at Toronto Pearson International Airport in Canada, according to the FAA and local authorities.

New videos show the moment a Delta flight from Minneapolis crash-landed, flipped and caught fire in Toronto. Officials say 21 people were injured when the Delta Air Lines plane flipped upside down while landing amid wintry conditions Monday at Toronto Pearson International Airport.

Representatives for Delta did not immediately respond to Reuters’ request for comment. TV reports said up to eight people were injured but there was no report on the extent of injuries. Of the eight injuries, one was critical and the rest were mild to moderate, Peel Regional Paramedic Services Supervisor Lawrence Saindon said.
