The Transportation Safety Board of Canada says it will release a preliminary report Thursday on a crash landing at Toronto Pearson Airport in Mississauga that sent 21 people to hospital last month.

The Delta Air Lines flight arriving from Minneapolis crashed on Feb. 17, leading to two closed runways the rest of the week and days of travel disruptions at Canada’s busiest airport.

All 76 passengers and four crew members survived when the plane burst into flames after flipping over and skidding on the tarmac.

All of those who were hospitalized were released within days of the crash.

The airline has offered US$30,000 in compensation to passengers, saying the money has “no strings attached.”

At least two lawsuits have been filed in the United States and a law firm in Canada has said that it’s been retained by several passengers.

Passengers on board the flight, among them 22 Canadians, and crew quickly evacuated the downed plane, which arrived in Toronto at around 2:15 p.m.

Speaking to reporters from across Canada and the U.S. at a press conference one day after the crash landing, the head of Pearson Airport said she was “grateful” nobody on board the inbound aircraft died.

Deborah Flint, president and CEO of the Greater Toronto Airports Authority, which operates Pearson, praised the flight attendants and flight crew on board the plane as well as first responders at Pearson.
