Delta Flight 4819 - Toronto, Canada - Wind and Snow

The Incident:

The aviation-weather incident I chose to discuss is the Delta Airlines Flight 4819 crash at Pearson International Airport in Toronto, Canada, on February 17, 2025. The Transportation Safety Board of Canada is investigating this event. (Canada, 2025)

The plane (Delta Flight 4819) attempted to land on a snowy runway at Pearson International Airport a little after 2 p.m. local time. (Canada, 2025) While landing, the plane had begun rolling towards its right side, probably due to winds causing lift on the left wing, and the right wing broke off. (Rodriguez, 2025) The plane continued rolling, the tail breaking off as well, until the plane stopped upside down, the nose pointing in a different direction. (Canada, 2025) When the right wing and tail broke from the fuselage, they caused a fire, that thankfully did not continue with the rest of the plane. There were thankfully no fatalities because of this, however, twenty-one people needed to go to the hospital for injuries. (Beresnevičius, 2025)

Why Pick This One:

I chose this event mainly for two reasons. First, this accident kept coming up non-stop when looking up recent aviation events and weather relations. The second reason was that no deaths had occurred due to this crash, which made me happy. Looking up most plane crashes, there is almost always a fatality, so the fact that this plane landed(crash-skidded?) then rolled over upside down and no one died, brought me some joy.

Personal Thoughts:

The weather played a significant role in causing this crash and preventing it from worsening after landing.

Crosswinds pushed the left wing up when the plane landed, causing an unintended roll. (Rodriguez, 2025) This, combined with the snow-covered ground, caused the landing gear to lose traction. When the wing and tail broke from the fuselage, a fire started. The cold climate prevented the fire from spreading to the wing and tail and prevented the fuselage from burning.
