LaGuardia collision leaves two pilots dead as investigators examine runway movements, staffing and emergency response

A week after a fatal collision at New York’s LaGuardia Airport, investigators are still piecing together how an Air Canada Express regional jet came to strike an airport fire vehicle on the runway shortly after landing.

The crash, which happened late on 22 March 2026 local time and was still dominating coverage through 23 and 24 March, killed the aircraft’s two pilots, injured dozens of other people and forced the closure of one of the United States’ busiest airports for much of the following day.

The aircraft involved was Air Canada Express Flight AC8646, a CRJ-900 operated by Jazz Aviation, arriving at LaGuardia from Montreal.

According to officials, it was carrying 72 passengers and four crew members.

The fire vehicle it hit was a Port Authority Aircraft Rescue and Firefighting unit, known as ARFF, which had been responding to a separate incident involving another aircraft.

In the days since the crash, the focus has shifted from the immediate rescue effort to a wider examination of what was happening across the airfield in the minutes before impact.

Questions have centred on runway clearances, the handling of a separate aircraft emergency, the workload of overnight controllers and the limits of the systems used to track vehicles moving on the ground.

Collision took place after landing

Authorities said the crash took place at about 11:37 pm on Sunday 22 March, shortly after the Air Canada aircraft landed at LaGuardia.

Kathryn Garcia of the Port Authority said the fire vehicle had been dispatched only minutes earlier to assist another plane that had reported an odour issue.

Air traffic control audio reviewed by multiple outlets appeared to capture the final moments before the impact.

In the recording, a controller can be heard warning the vehicle to stop as it crossed the runway.

Seconds later, the Air Canada jet struck it.

Photographs from the scene showed the aircraft badly damaged, with the cockpit area torn apart and the rear section resting low to the ground.

The truck was left overturned and heavily damaged nearby.

The National Transportation Safety Board has since said that both the aircraft and the fire vehicle had been cleared to cross the runway, making runway movement and communication a central part of the investigation.

Chair Jennifer Homendy said the inquiry would include cockpit voice recordings, tower communications, surveillance footage and interviews with the controllers who were on duty that night.

Two pilots killed, dozens injured

The two pilots who died were identified as Antoine Forest and Mackenzie Gunther.

Their deaths became an immediate focus in both the United States and Canada, where the flight had originated.

FAA administrator Bryan Bedford described them as two young men at the start of their careers, while Canadian coverage also highlighted Forest’s background as a French-speaking Quebecer.

The Port Authority said 41 people were taken to hospital after the collision.

Early reports varied slightly on the number later discharged, but authorities consistently said that most of those injured were treated and released, while others remained in hospital with more serious injuries.

The two officers in the ARFF vehicle, Sergeant Michael Orsillo and Officer Adrian Baez, were both injured but were reported to be in stable condition.

Baez was later released from hospital, while Orsillo remained under care.

Accounts from passengers suggest that the force of the collision created confusion inside the cabin, with some travellers unsure at first what had happened.

One passenger told The New York Times that the aircraft landed hard, a loud grinding noise followed and the plane then jolted violently.

Another said passengers quickly realised they needed to get out, even though they had little direction in the immediate aftermath.

One of the flight attendants, Solange Tremblay, was reportedly ejected from the aircraft while still strapped into her seat.

Her daughter told a Quebec broadcaster that she suffered a broken leg and required surgery, but survived.

Separate emergency appears central to timeline

A major strand of the investigation concerns the fact that controllers were already handling another issue before the collision.

According to officials and air traffic audio, a United Airlines aircraft had aborted a take-off after reporting an unusual odour in the cabin.

Flight attendants on that aircraft were said to be feeling ill, prompting an emergency response.

The fire truck involved in the LaGuardia collision was being sent to that separate aircraft when it crossed the path of the arriving Air Canada flight.

Audio suggests controllers were continuing to relay messages about the United aircraft while also directing ground movements elsewhere on the airfield.

That overlap has intensified scrutiny of the workload inside the tower at the time.

The NTSB confirmed that two controllers were in the cab during the midnight shift.

One was handling local control duties for take-offs and landings, while the other, described as the controller in charge, also held supervisory responsibilities.

Investigators said they were still establishing exactly who had responsibility for aircraft and vehicle movements on the ground at the moment of the crash.

Staffing and combined positions under scrutiny

CNN’s reporting focused heavily on long-running concerns about staffing shortages in US air traffic control.

Former controllers and aviation analysts told the network that combining positions late at night is common when traffic levels fall, but becomes far more problematic when demand rises unexpectedly or an emergency develops.

That appears relevant to LaGuardia, where late-night traffic may have been heavier than usual because of earlier weather disruption and delays.

Homendy said there is a broader systemic concern when roles are combined because of short staffing, especially in a high-workload environment.

She also said controllers themselves have raised such concerns for years.

The issue is familiar to federal investigators.

Coverage pointed to earlier findings from the January 2025 collision near Ronald Reagan Washington National Airport, where investigators said an overloaded controller managing combined positions was among the contributing factors.

A 2024 independent FAA panel had also warned that combined positions can reduce safety margins, particularly during busy periods, overnight shifts or emergencies.

At the same time, some current and former aviation officials have urged caution about drawing conclusions too early.

Transportation Secretary Sean Duffy said LaGuardia was generally well staffed overall, with 33 of 37 controller positions filled and seven more trainees in the pipeline.

Others noted that reduced staffing overnight can be standard practice when traffic is expected to be lighter.

Technology and surface tracking also in focus

Homendy also drew attention to the technical side of the accident.

She said a ground radar system that might have provided an alert before the collision did not do so.

She added that the fire truck did not have a transponder, which would have helped the system detect it more effectively.

That has fed into broader criticism of the age of US air traffic control infrastructure.

Homendy described the system as old and said controllers need better tools to monitor ground movements involving both aircraft and vehicles.

CNN’s coverage tied those comments to wider federal efforts to modernise the system, including a long-term plan announced by the Department of Transportation and concerns that controllers are still working with outdated technology in critical areas.

The New York Times also noted that the FAA has spent several years trying to reduce runway incursions after a series of close calls in 2023.

Those efforts included safety reviews, grants to airports and work on alerting systems designed to warn crews about aircraft or vehicles in the wrong place.

Even so, the LaGuardia collision has shown how vulnerable the system remains when multiple defences fail at once.

Airport disruption and operational impact

The crash closed LaGuardia for much of Monday 23 March, with flights resuming on a limited basis at 2 pm More than 500 flights were cancelled by Monday morning, and some reports later put the total disruption above 600 flights as the backlog continued.

Incoming services were diverted to John F.

Kennedy and Newark Liberty airports, while road closures and traffic delays affected access around LaGuardia itself.

As a major airport focused on regional and domestic routes, LaGuardia’s closure quickly spread disruption across the eastern United States and nearby Canadian cities.

Delta, the airport’s largest carrier, was among the airlines forced to cancel or rebook large numbers of passengers.

The shutdown also collided with wider transport strain linked to a partial federal government shutdown in the United States.

The New York Times reported that long Transportation Security Administration lines delayed the arrival of NTSB specialists, slowing the first full day of on-site investigation.

Canadian response and Air Canada controversy

In Canada, the crash prompted both official support for the investigation and political controversy around Air Canada’s response.

Canadian authorities said they were working closely with US investigators, and the Transportation Safety Board of Canada sent a team to assist.

At the same time, Air Canada chief executive Michael Rousseau came under criticism after issuing a condolence message only in English, despite the deaths of two Canadian pilots and the fact that one of them, Antoine Forest, was from Quebec.

Rousseau later apologised for his inability to speak French adequately, but the issue escalated in Quebec, where lawmakers passed a motion calling for his resignation.

That debate sat alongside broader Canadian concern about the safety issues raised by the crash, particularly the condition of the US air traffic control system.

Investigation continues

One week on, the main facts are clear, but the cause is not.

A landed passenger jet struck an airport fire vehicle that was responding to another emergency.

Two pilots died, dozens of others were injured and LaGuardia’s operations were badly disrupted.

What remains unresolved is how the runway came to be occupied by both the aircraft and the truck at the same time.

Investigators are now examining not just the decisions made in the tower that night, but the wider operating environment around them: staffing, fatigue, late-night procedures, communications, vehicle visibility and the resilience of the airport surface safety system.

The findings are likely to matter far beyond LaGuardia.
