All 21 people who were hospitalized after a Delta Air Lines flight crashed and overturned in Toronto this week have been released from the hospital, the airline said.

Toronto Pearson International Airport reported Monday afternoon that a Delta flight arriving from Minnesota was involved in an “incident” while making its landing. The plane ended up on the runway where it appeared to be upside down.

A Delta Air Lines commuter jet crashed at Toronto Pearson Airport without fatalities. The plane, landing in severe weather, flipped over, but all 80 people on board survived. The NTSB and Canadian authorities are investigating the incident.
