After Delta Flight 4819’s cabin rolled upside down and came to rest in a terrifying crash landing at Toronto Pearson International Airport, a flight attendant stood on what had been the ceiling – one leg propped on an upturned baggage compartment – and addressed passengers who’d unbuckled themselves from inverted seats.

Delta Air Lines released new details about the crew aboard flight 4819, operated by its subsidiary Endeavor Air, which crash-landed in Toronto on Monday.
