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.”

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.
