The NTSB has published a preliminary report on the February 25 near-collision runway incursion involving a Flexjet Bombardier Challenger 350 and a Southwest Airlines (SWA) Boeing 737-800 at Chicago Midway International Airport (KMDW). The Aviation Investigation Preliminary Report noted that the “cockpit voice recorders for both airplanes were overwritten,” although the “SWA flight data recorder (FDR) and data from the Flexjet FDR were sent to the NTSB’s Vehicle Recorder Laboratory in Washington, D.C. for analysis.”

The incursion resulted in the SWA 737 crew aborting the landing on Runway 31C and performing a go-around after Flexjet Flight 560 (LXJ560) crossed the active runway in front of the 737. The 737 passed less than 200 feet behind the Challenger, according to the NTSB.
