The pilot and copilot were killed in the late Sunday night collision, which crushed the nose of the aircraft, while around 40 passengers and crew members were taken to area hospitals, some with serious injuries. Most have since been released from treatment, authorities said Monday.

Two Port Authority employees who were traveling in the fire truck also suffered injuries that were not believed to be life-threatening, aid Kathryn Garcia, executive director of the Port Authority of New York and New Jersey, which operates the airport.

In the moments before the crash, an air traffic controller could be heard on a radio transmission giving clearance to a vehicle to cross part of the tarmac, then trying to stop it.

The airport was shut down and air traffic was diverted, and on Monday morning operations also were halted at Newark Liberty International Airport in neighboring New Jersey. Air traffic controllers evacuated the tower because of a burning smell from an elevator, the Federal Aviation Administration said.

The shutdowns happened during long waits for travelers due to the busy spring break travel season and a shortage of Transportation Security Administration officers because of a lack of routine funding for the Department of Homeland Security.

Pilot and copilot were based out of Canada

The pilot and copilot who died were both based out of Canada, Garcia said during a news conference.

The airport will remain closed until at least 2 p.m. Monday to facilitate the investigation, which is being led by the National Transportation Safety Board.

“Two pilots were killed and dozens injured in this tragedy. Our thoughts are with the victims, their families, and everyone affected,” New York Gov. Kathy Hochul posted online.

The fire truck was traveling across the runway to respond to a separate incident aboard a United Airlines flight, whose pilot had reported “an issue with odor,” said Garcia, who deferred additional questions about the sequence of events leading up to the crash to the NTSB.

There were 72 passengers and four crew members aboard the aircraft, a Jazz Aviation flight operating on behalf of Air Canada, according to a statement from the airline. The flight originated at Montreal-Pierre Elliott Trudeau International Airport, the major airport serving Montreal.

Photos and videos from the scene showed severe damage to the front of the aircraft, with cables and debris hanging from a mangled cockpit. Nearby, a damaged emergency vehicle lay on its side.

Stairways used to evacuate passengers from the aircraft were pushed up to the emergency exits on the jet, a Bombardier CRJ. The impact left the jet with its crumpled nose tilted upward.

Air traffic controller tried to stop vehicle after giving clearance

The air traffic controller tried to warn the vehicle.

“Stop, Truck 1. Stop,” the transmission says. The controller can then be heard frantically diverting an incoming aircraft from landing.

Air traffic controllers are not impacted by the partial government shutdown that has caused long delays at airport security checkpoints in recent days. They have been affected by past shutdowns.

As passengers straggled out of the airport into the dark early Monday, some described having arrived at LaGuardia hours before their flight, hoping to beat the lines.

Arturo Davidson said his Miami-bound flight was on the tarmac Sunday night when fellow passengers saw the collision or its aftermath and reactions rippled through the cabin.

The passengers were soon told there had been an accident. About 20 minutes later, they were informed the airport was closing and they must return to the terminal, he said later Monday, gazing at a departure board filled with cancellations.

“I don’t think we’re going at two,” he sighed, referring to the time Monday afternoon that officials gave as the earliest for reopening LaGuardia.

One of the nation’s busiest airports

LaGuardia was 19th busiest in 2024 out of more than 500 U.S. airports, with over 16.7 million passengers boarding there, according to a 2025 FAA database.

The airport, which opened to commercial traffic in 1939, covers 680 acres (275 hectares) and borders Flushing and Bowery bays in Queens. The Port Authority of New York and New Jersey describes it as “one of the nation’s leading domestic gateways for business and leisure travel” in its 2024 Airport Traffic Report.

LaGuardia is one of 35 major airports across the country equipped with an advanced surface surveillance system that uses radar and data from locator systems on planes to alert controllers to potential conflicts on runways, according to the FAA.

There are three different models of Aircraft Rescue and Firefighting trucks, according to a video put out last year about the unit by the Port Authority. One carries 1,500 gallons (5,678 liters) of water and firefighting chemicals. Two others carry 3,000 gallons (11,356 liters) of water. One of those models is also equipped with a turret that can extend 65 feet (20 meters) to penetrate inside an aircraft and discharge firefighting chemicals.

It’s still too early to tell what went wrong, and investigators from the NTSB will now start collecting facts, interviewing people, downloading recordings and reviewing data from flight recorders, aviation safety expert Jeff Guzzetti said.

“It might be easy enough just to say, ‘Oh, the controller made a mistake.’ But there’s got to be deeper questions,” he said.
