Southwest Airlines Flight 1248 (2005)
A Boeing 737 slid off a snow-covered runway at Chicago Midway airport, broke through a perimeter fence, and struck two cars on a roadway, killing a 6-year-old boy and injuring several passengers.
The NTSB found the flight crew failed to properly account for runway conditions and did not use reverse thrust soon enough after landing long.
The crash prompted changes in how airlines calculate landing distances in wintry conditions.
A runway overrun that killed someone off airport grounds, raising the same questions about landing distance and crew decision-making now at issue in Miami.
