Newly released air traffic control audio from LaGuardia Airport has provided a harrowing window into the final seconds before Air Canada Express Flight AC8646 collided with a Port Authority fire truck on Runway 4, killing both pilots on the night of March 22, 2026. The recordings, captured by monitoring services and partially shared by media outlets, capture the escalating tension in the tower and the desperate attempts to avert disaster as the CRJ-900 approached its landing.

The flight from Montreal had been routine until the critical final phase. A United Airlines aircraft had earlier reported an unusual cabin odor, prompting the dispatch of fire and rescue vehicles. The Port Authority fire truck, designated “Truck 1,” received clearance to cross the active Runway 4 at taxiway Delta to position for that response. Moments later, as the Air Canada jet descended on short final, the conflict became apparent.

In the released audio, the controller’s voice shifts from procedural calm to urgent alarm. Clearances for the landing aircraft and the ground vehicle overlap fatally. The controller then issues frantic, repeated commands directed at the fire truck: “Stop, stop, stop! Truck 1, stop! Stop, Truck 1, stop!” The word “stop” is heard at least ten times in rapid succession, growing more strained and desperate with each repetition as the controller tries to halt the vehicle. Additional instructions divert other traffic, including telling one aircraft to go around and hold positions for others.

The pilots of the Air Canada flight are heard acknowledging landing clearance earlier in the sequence with standard read-backs, maintaining professional composure. No public transcripts have yet detailed any last words spoken by Captain Edward Daniel Murphy or First Officer Antoine Forest inside the cockpit itself, as the cockpit voice recorder remains under NTSB analysis. However, the tower transmissions reflect the split-second window in which the crew would have seen the developing emergency. Aviation experts note that in such scenarios, pilots focus on maintaining aircraft control, configuring for the landing, and preparing for any go-around or emergency maneuvers—actions consistent with the relatively controlled “skating” slide described by survivors after impact.

Roughly 20 minutes after the collision, the audio captures the emotional aftermath in the tower. One controller, clearly shaken, says, “I messed up.” Another responds supportively: “Nah man, you did the best you could.” A third voice from an airborne aircraft remarks, “Man, that wasn’t good to watch.” These exchanges, now widely circulated, underscore the human toll on everyone involved in the high-pressure environment of busy airport operations.

The impact itself was devastating. The jet, still carrying significant speed after touchdown, struck the fire truck, shearing off much of the cockpit and forward fuselage. Both pilots died instantly from catastrophic injuries, while 41 passengers and crew sustained injuries ranging from fractures and concussions to lacerations. The aircraft’s rear and mid sections remained intact enough for flight attendants to execute a rapid evacuation using emergency slides and overwing exits. Survivors described screams filling the cabin, a violent forward jerk, and the surreal sensation of the plane sliding before coming to a stop.

The National Transportation Safety Board, working with the FAA, Transport Canada, and the Canadian Transportation Safety Board, has recovered both the flight data recorder and cockpit voice recorder. These will provide critical insight into any communications or actions taken by the pilots in their final moments. Early investigation lines focus on clearance protocols, tower workload during the late-night shift, the effectiveness of surface detection systems like ASDE-X, and procedures for allowing emergency vehicles to cross active runways during arrivals.

LaGuardia’s constrained layout—bordered by water and dense urban areas—has long complicated ground movements, making precise coordination essential. This incident has intensified calls for reforms, including stricter hold-short enforcement, automated conflict alerts, physical barriers for emergency crossings, and better workload distribution in control towers.

Air Canada and Jazz Aviation have expressed deep sorrow for the loss of the two pilots, confirming full support for their families and all those affected. The airline emphasized the crew’s professionalism throughout the emergency. Tributes continue to pour in for Captain Murphy and First Officer Forest, remembered as dedicated aviators who embodied the highest standards of their profession.

The released audio does not contain dramatic final declarations from the pilots but instead reveals the controlled urgency of professional communication right up to the point of impact. In aviation, the absence of panic in the cockpit voice recorder often speaks to the training and composure that pilots maintain even in extremis. Their last actions—keeping the aircraft as stable as possible—likely gave the cabin crew the seconds needed to save the lives of everyone behind them.

As the full investigation unfolds, the partial audio already serves as a stark reminder of how quickly routine operations can turn catastrophic when clearances misalign by mere seconds. The repeated, increasingly desperate “stop” commands from the tower, followed by the quiet admission of error afterward, have left listeners chilled and reflective.

For the families of the pilots, the surviving passengers, and the aviation community, these recordings capture not just a sequence of events but the human reality behind every flight: split-second decisions, enormous responsibility, and the thin margin between safety and tragedy. The pilots’ final transmission may have been standard procedure, yet their legacy is written in the lives they helped protect in their final moments.

The haunting radio audio stands as both evidence and memorial—a sobering record of the seconds that changed everything at LaGuardia.
