In the summer of 2025, a pilot landing at LaGuardia Airport filed an urgent safety report with federal aviation officials. Air traffic controllers had cleared an aircraft for takeoff while the pilot’s plane was just 300 feet from touching down on an intersecting runway.

“Please do something,” the pilot wrote. “The pace of operations is building in LGA. The controllers are pushing the line.”

The warning went unheeded. On Sunday night, the consequences became clear.

An Air Canada Express flight from Montreal collided with a Port Authority fire truck on Runway 4, killing both pilots and injuring more than 40 passengers and crew. The regional jet was traveling between 93 and 105 miles per hour when it struck the emergency vehicle, which had been cleared to cross the active runway while responding to a separate incident.

The collision was not unpredictable. It was, according to dozens of anonymous pilot reports filed to NASA’s Aviation Safety Reporting System, the inevitable result of an air traffic control system under extreme stress.

The Warnings That Went Nowhere

The NASA database, which collects confidential safety reports from pilots and air traffic controllers, contains multiple warnings about LaGuardia in the months preceding Sunday’s crash.

One pilot, writing during Canadian wildfire smoke that blanketed the East Coast last summer, described how controllers had initiated a takeoff clearance when their aircraft was “only 300 feet high on final” approach. The departing aircraft hesitated before beginning its takeoff roll. “I think he or she thought twice,” the pilot wrote.

Faced with poor visibility and uncertainty about a possible helicopter in the area, the pilot continued the approach rather than executing a go-around maneuver. “Otherwise,” they wrote, “I would have been suddenly going around and trusting that the helicopter was not near the departure end.”

The pilot noted that runway lighting systems had been turned off and that air traffic control guidance “does not seem to give guidance on exactly how close aircraft in this situation can get.”

Another report filed since January 2025 described how an aircraft was cleared to cross a runway while another plane was landing. “We noticed an aircraft we thought was landing seemingly headed for us,” the pilot wrote. “Air traffic control should have sent the aircraft around.”

Most chillingly, one pilot drew an explicit parallel to the January 2025 mid-air collision over the Potomac River that killed more than 60 people. “On thunderstorm days, LGA is starting to feel like [Ronald Reagan National Airport] did before the accident there.”

A Controller’s Admission

Sunday’s crash unfolded against a backdrop of chaotic runway operations. A United Airlines flight had twice aborted takeoff and reported an odor sickening flight attendants. With no gate available, controllers dispatched fire trucks to the stranded aircraft.

One of those trucks, carrying Port Authority officers Adrian Baez and Sergeant Michael Orsillo, was cleared to cross Runway 4. Moments later, air traffic control issued frantic instructions: “Stop, stop, stop, Truck 1. Stop, stop, stop.”

The warning came too late. The Air Canada jet, a Bombardier CRJ-900 operated by Jazz Aviation, slammed into the fire truck at speed.

Roughly 20 minutes after the collision, a controller’s voice was captured on recording: “We were dealing with an emergency, and I messed up.”

A System Under Strain

The collision occurred amid a partial U.S. government shutdown that began in mid-February, caused by a Senate dispute over immigration enforcement. Hundreds of Transportation Security Administration agents have called in sick or quit rather than work without pay, creating security line delays that have rippled through the entire aviation system.

National Transportation Safety Board Chair Jennifer Homendy revealed Monday that one of her investigators was stranded in a Houston security line for three hours. The agency had to “beg” to get the specialist through, she said.

The staffing crisis extends to air traffic controllers. The Federal Aviation Administration has faced a shortage of approximately 3,000 controllers nationwide, forcing existing staff to work overtime and six-day weeks. Training backlogs from previous government shutdowns have compounded the problem.

Transportation Secretary Sean Duffy, confirmed the day before the Potomac collision, declined to say how many controllers were on duty at LaGuardia when Sunday’s crash occurred. He described the tower as “very well staffed” with 33 certified controllers against a target of 37.

Former FAA air traffic control chief Mike McCormick noted that while LaGuardia is “not a control tower that has perennial staffing problems,” overnight shifts are typically staffed more lightly.

The Human Cost

The two pilots killed were identified as Antoine Forest of Coteau-du-Lac, Quebec, and Mackenzie Gunther, a 2023 graduate of Seneca Polytechnic’s aviation program. Both were described as young aviators at the beginning of promising careers.

Forest had been flying since age 16, starting with bush planes before joining Jazz Aviation in December 2022. His great-aunt, Jeannette Gagnier, recalled a young man “always taking courses and flying. He never stopped.”

Flight attendant Solange Tremblay, seated in the cockpit jump seat, was thrown 320 feet from the aircraft when the nose collapsed. She survived with multiple fractures—a fact her daughter called “a complete miracle.”

Passengers credited the pilots with preventing greater loss of life. “I felt like the pilots saved our lives,” survivor Rebecca Liquori told CNN. “They’re the reasons I was able to make it home safe to see my boys.”

Safety analysts agreed. CNN’s David Soucie noted that the aircraft struck the fire truck directly in its center, pushing the vehicle forward rather than shearing it. Had the truck been 40 feet farther back, the impact could have ruptured fuel cells and ignited a fire.

A Pattern of Near-Misses

Sunday’s fatal collision was not LaGuardia’s only recent incident. In October, two Delta jets collided on a taxiway, sending one person to the hospital. In July, a co-pilot reported a near-collision after controllers cleared a plane to cross a runway while another aircraft was landing.

“Ground control issued a stop command just in time,” that report stated.

The National Transportation Safety Board has recovered the cockpit voice recorder and flight data recorder from Sunday’s crash. Both were undamaged and have been sent to Washington for analysis. Runway 4 will remain closed until at least Friday as investigators process what Homendy described as a “tremendous amount of debris.”

The agency has not yet determined whether the fire truck was visible on the airport’s surface detection equipment—a ground radar system designed to track aircraft and vehicles on runways.

Questions Without Answers

What remains unclear is whether anyone with authority read the NASA safety reports, or what actions—if any—were taken in response.

The aviation safety reporting system is designed to identify systemic risks before they become catastrophes. Pilots file reports anonymously in exchange for immunity from disciplinary action, creating a database of near-misses and hazardous conditions.

But the system only works if someone acts on the information.

At LaGuardia, one of the nation’s busiest airports operating in some of its most congested airspace, the warnings accumulated. The pace of operations built. Controllers pushed the line.

Then, on a foggy March night, the line snapped.
