Scary incident on Delta Air Lines ... a plane crashed and flipped upside down after landing.

Footage from Toronto Pearson International Airport shows the fuselage flipped over on a snowy runway ... with emergency crews responding.

Smoke is billowing from the fuselage and the exterior of the Delta commercial jet looks burned ... and it appears the wings and tail are broken off.

The airport says the incident happened Monday when a Delta flight from Minneapolis was landing.

The airfield is being cleared of ice and snow after a weekend storm, and it looks like the weather may have played a role here.

Fortunately, Toronto Pearson says "all passengers and crew are accounted for."
