A Delta Connection Bombardier CL-600-2D24 Regional Jet CRJ-900LR, flight EDV4819 operated by Endeavor Air, was destroyed following a landing accident on runway 23 at Toronto Pearson International Airport (YYZ/CYYZ), Toronto. Ontario. The four crew members and seventy-six passengers survived, but eighteen people were injured, three of them seriously. Several videos captured the accident sequence. On touchdown, the right hand main gear collapsed, causing a fire and the right wing to contact the ground. The wing dragged along the runway surface for about 3 seconds before the aircraft flipped inverted. A post crash fire ensued which was (mostly) contained by airport emergency services. Photos from the scene shows that the right wing had separated and the aircraft came to rest inverted. The main gear and tail control surfaces were impact damaged and separated as well. The left wing and nose gear remained attached to the airframe.
