Delta Air Lines has announced that 19 of the 21 passengers hospitalized following a plane crash in Toronto have been successfully released, as investigations into the crash continue. The incident occurred on February 17 at Toronto's Pearson Airport when a regional jet operated by Endeavor Air, a subsidiary of Delta, flipped over upon landing. The Reuters reported that authorities are looking into the causes of the crash with assistance from the U.S. National Transportation Safety Board and Transport Canada.

According to officials, the aircraft, a CRJ900 made by Bombardier, had been encountering severe weather conditions including gusting crosswinds and blowing snow due to a recent snowstorm that deposited over 22 centimeters (approximately 8.6 inches) of snow at the airport. The Transportation Safety Board of Canada confirmed that parts of the plane separated upon landing, and a fire broke out shortly thereafter. Channel News Asia noted that the two remaining hospitalized passengers are not facing life-threatening injuries.

Flight 4819, which had departed from Minneapolis-St. Paul International Airport, touched down around 2:13 p.m. local time. The plane's landing was characterized as firm, prompting scrutiny from aviation experts on the unusual descent. Ken Webster, Senior Investigator with the Transportation Safety Board, stated, "Air crashes are usually caused by multiple factors," reiterating that the investigation is still in its early phase. Video footage shared on social media captured the jet's landing which appeared to lack the typical flare maneuver pilots execute before touchdown, raising further questions about the landing technique employed.

Passenger accounts describe moments of confusion and calmness during the chaos. One passenger expressed feelings of disbelief when the aircraft began to flip before coming to rest on its side. As rescue efforts and investigations proceed, Delta Air Lines aims to provide comprehensive support for those involved. Further details on the investigation's findings will be shared as they become available, with the black boxes sent for lab analysis to uncover the crash's causes, according to South China Morning Post.

The wreckage of the aircraft may take an additional 48 hours to remove, causing delays in operations at Toronto Pearson Airport. Air Canada has indicated that cancellations and delays have affected over 1,290 flights over the past six days, further complicating the airport's busy operations.
