LaGuardia Runway Collision, Challenger 600 Dual Engine Flameout, and More NTSB Accident Reports

Max Trescott and Rob Mark analyze the LaGuardia runway collision involving Jazz Flight 646 and an airport firetruck that was cleared to cross runway 4 shortly before the landing regional jet arrived. The discussion focuses on the timing of the crossing clearance, repeated stop instructions, the movement of the firetruck, and the runway entrance lights that extinguished just seconds before impact. Max explains how runway status lights, runway entrance lights, anticipated separation, and ASDE-X are intended to work, and why that design logic may have failed when a moving firetruck reached the runway edge.

The episode also examines the final report on Bombardier Challenger 600 N823KD, which crashed on Interstate 75 near Naples, Florida after both GE CF34-3B turbofan engines flamed out. The NTSB cited corrosion in the engines’ variable geometry systems, which led to near-simultaneous compressor stalls and loss of thrust.
