== NEW YORK — The sequence of events leading to the fatal collision between an Air Canada jet and a fire truck at LaGuardia Airport on March 22 centers on a controller's authorization for the emergency vehicle to cross a runway just 12 seconds before the aircraft's landing. == Investigators from the National Transportation Safety Board (NTSB) confirmed this detail, highlighting the extremely compressed timeframe in which the incident unfolded. A subsequent order for the fire truck to stop, issued nine seconds before impact, came perilously close to the plane's touchdown, leaving scant opportunity to avert disaster.
The NTSB is examining multiple safety failures, including the functioning of the airport's runway status lights, which, if operational, might have alerted the fire truck driver to desist, even with the controller's clearance. The probe is also assessing whether the airport's overnight staffing levels of two air traffic controllers are adequate and who was specifically responsible for coordinating ground and air traffic.

Further complicating the picture, reports suggest investigators are exploring the possibility that an air traffic controller may have momentarily stepped away from their post prior to the collision. While no definitive conclusions have been drawn, this line of inquiry forms part of a broader investigation into potential vulnerabilities within the U.S. air traffic control system, which is currently experiencing significant staffing pressures. The accident, which claimed the lives of the two Air Canada pilots, marks LaGuardia's first fatal incident in over three decades. Firefighters aboard the truck and passengers on the plane sustained no fatalities.
Investigating the Chronology
The moments preceding the crash paint a stark picture of a rapidly deteriorating situation:
17 seconds before impact: The fire truck acknowledged the controller's clearance to cross the runway.
12 seconds before touchdown: The controller issued the authorization for the fire truck to cross.
9 seconds before impact: The tower issued a stop command to the fire truck.
8 seconds before impact: The aircraft's landing gear touched down on the runway.
4 seconds before impact: The tower issued another command for the fire truck to stop.
Contextualizing the Incident
The collision occurred late on the evening of March 22. The investigation is also focusing on the cockpit voice recorder of the Air Canada plane and the distinct responsibilities assigned to each of the two controllers on duty. Interviews are being conducted with the controllers and the firefighters involved in the incident. The specific equipment aboard the fire truck that would have triggered runway warning systems is also under review.
