Southwest Airlines Flight 1248 crash at Midway (2005)
A Southwest Airlines 737 landed at Midway in heavy snow, failed to stop, and overran Runway 31C. The jet tore through a fence and onto Central Avenue, striking a car and killing a six-year-old boy; several other people were hurt.
The crash focused national attention on the danger of runway overruns and on the fact that Midway's runways lacked long safety areas or arresting systems.
It helped drive the deployment of EMAS-style arresting beds at airports where space for a standard runway safety area doesn't exist.
The same kind of overrun protection that would have caught the 2005 plane is what's damaged and now under repair at Midway. Its temporary absence means planes on Runway 22L lose a last-resort safety feature.
