“When planes land with the crosswind, when they point the nose of the planes, it’s called a crab, into the wind, the plane tracks straight.”

A Delta Connection CRJ-900 flipped onto its roof landing in Toronto, and all 80 people aboard survived. Winds gusted 35 to 40 knots. A former pilot says that was near the plane’s limit and the crew should not have tried. The approach speed and pattern looked normal.
