132 knots touchdown speed according to the Chicago Tribune:
Runway conditions at the time a Southwest Airlines jetliner touched down during a snowstorm Thursday night at Midway Airport were "fair" for most of the strip but "poor" toward the end, federal investigators disclosed this afternoon.
Now they are trying to determine why Flight 1248 from Baltimore-Washington International Airport ran off the end of the runway, crashed through a concrete barrier and fence and smashed into vehicles on Central Avenue.
A 6-year-old boy riding in one car was killed. At least 10 other people—eight on the ground and two on the plane—were injured. Midway was shut down immediately after the accident, stranding some 600 travelers overnight. The airport reopened at 6 a.m. today.
Investigators hope to complete their site review and move the airliner from the street to an airport hangar Saturday, said Ellen Engleman Conners, a board member of the National Transportation Safety Board who is leading the inquiry.
Speaking at a late afternoon news conference, she detailed the sequence of events leading to the crash.
"The airplane had been in a normal hold position. The approach was normal with normal conversations. The crew did not mention problems with the airplane," she said.
"Air traffic control reported runway braking to be fair on most of the runway and poor at the end. Touchdown was normal. There was a slight bounce. There was a 7- to 8-knot tailwind. There was 32 seconds from touchdown until the aircraft hit the fence."
"Excellent" and "pristine" data has been recovered from the Boeing 737-700's flight data and cockpit voice recorders, Engleman Conners said.
Among other things, data showed the plane was going 132 knots, or 152 m.p.h., when it touched down at 7:14 p.m. Thursday on Midway's Runway 31 Center. It was traveling about 40 knots, or 46 m.p.h., when it went through the fence on the northwest corner of the airport.
