There was drifting snow.
There were strong winds coming from the west at about 29 miles per hour, with gusts of up to 38 miles per hour, around 2:15 p.m., the time of the crash, according to the authorities. There was also drifting snow in Toronto, which was struck by two snowstorms in the past few days.
The weather advisories for Toronto Pearson International Airport at the time of the crash “indicated a gusting crosswind and blowing snow,” according to Flightradar24, an aviation tracking website.
The cause of the crash will be investigated by the Transportation Safety Board of Canada, which will be assisted by a team of American investigators from the Federal Aviation Administration.
There were 76 passengers onboard.
The flight had a crew of four, according to Delta, and the rest were passengers. Of those, 22 were Canadians.
Some of the injured were taken to hospitals but most passengers were taken to a Sheraton Gateway Hotel, near the airport’s terminals.
They left around 7 p.m. local time, picked up by taxis and family members, a hotel staff member said, declining to provide more details.
Operations at the airport resumed at 5 p.m. local time although two of the five runways remain closed.
The plane was a Bombardier jet.
The model CRJ900 aircraft was operated by Endeavor Air, a Delta subsidiary that typically operates smaller planes for the airline.
It was about 16 years old, according to F.A.A. records. With regular maintenance, such passenger jets are often operated for two to three decades, or more.
More than 380 CRJ900s are used by airlines around the world, according to Cirium, an aviation data company. The aircraft, which has been in operation for more than two decades, has a solid safety record, according to Cirium data.
