Earlier this afternoon, the flight data recorder and cockpit voice recorder were recovered and sent to the NTSB laboratory in Washington for downloading and analysis. The NTSB interviewed the pilots, collected witness accounts and video. The NTSB has reported that evidence from video and other sources is consistent with the Southwest Boeing 737-700 nose gear making contact with the runway before the main landing gear. 

The flight data recorder on the airplane recorded 1,000 parameters and contained approximately 27 hours of recorded data, including the entire flight from Nashville to New York. The cockpit voice recorder contains a two hour recording of excellent quality that captures the entire flight from Nashville to New York and the accident landing sequence. 

The flaps were set from 30 to 40 degrees about 56 seconds prior to touchdown. The altitude was about 32 feet, airspeed was about 134 knots, and pitch attitude was about 2 degrees nose-up approximately 4 seconds prior touchdown.
