An Air Canada jet collided with a fire truck at LaGuardia Airport in Queens on Sunday night, killing two people and injuring dozens. The fire truck was responding to an unrelated incident when the crash happened.

Audio from air traffic control, flight data and imagery of the aftermath provide clues as to how the collision unfolded.

Before the crash

After multiple attempts at takeoff and reporting an issue with an odor, a United Airlines plane on the east side of the airport requested assistance. A Port Authority Aircraft Rescue and Firefighting truck responded and began traveling across the airport toward the United plane.

At the same time, around 11:36 p.m. an Air Canada Express Flight 8646 approached Runway 4 at about 150 miles per hour, according to flight data.

Fire truck cleared to cross runway

About 30 seconds before the collision, which was around 11:37 p.m., the fire truck requested permission from air traffic control to cross Runway 4 at crossing “D.” An air traffic controller promptly granted access, responding “Truck 1 and company, cross 4 at delta.”

Ten seconds after granting permission and about 10 seconds before the collision, the same controller is heard saying, “Stop, stop, stop, stop, Truck 1, stop, stop, stop.”

Flight data shows that the Air Canada plane touched down on the runway about 15 seconds before the collision with the fire truck.

About 10 seconds before the crash, the controller said, “Stop, Truck 1, stop!”

In the six seconds between when the controller told Truck 1 to stop the first time and the second time, the United flight covered approximately 1,000 feet, traveling about 200 feet per second, or 130 miles per hour, according to analysis of the flight data.

Moment of crash

Surveillance footage reviewed by The New York Times shows the Air Canada flight traveling down the runway and approaching the intersection where the fire truck had requested permission to cross. As the fire truck made a left turn onto Runway 4, the plane collided into the back half of the truck around 11:37 p.m.

Before the crash, one passenger, Rebecca Liquori, 35, said that there was turbulence as the flight prepared to land and that a flight attendant gave a warning about what to do in case of a possible emergency landing.

Using the length of the plane as a reference scale, The Times estimated the speed of the plane in the video footage to be about 110 miles per hour right before impact.

After the crash, the plane traveled about an additional 600 feet down the runway before coming to a stop off to the side of the runway. The fire truck was knocked onto its side and also slid down the runway before coming to a halt on a grassy median.

Aftermath

Images and video of the aftermath show that a large portion of the front of the airplane, including most of its cockpit, was torn off or crushed by the impact. Both the pilots died in the collision. A flight attendant, Solange Tremblay, was ejected from the plane while still strapped into her seat, sustaining a fractured leg.

The Trump administration placed a statue of Christopher Columbus on White House grounds over the weekend, doubling down on its efforts to commemorate the 15th-century explorer.

“As we celebrate our Nation’s 250th anniversary of independence, the White House is proud to honor Christopher Columbus’s legendary life and legacy with a well-deserved statue on the White House grounds,” Davis Ingle, a White House spokesperson, said in a statement. “In this White House, Christopher Columbus is a hero, and President Trump will ensure he’s honored as such for generations to come.”

The statue is a replica of the one that used to sit in Baltimore’s Little Italy, according to John Pica, a Maryland lobbyist and president of the Italian American Organizations United. In 2020, after the killing of George Floyd by a white police officer and a reckoning on racial justice issues in the U.S., protesters pulled the statue down and hurled it into the city’s Inner Harbor.

The marble statue depicted Columbus facing east towards the sun, and was dedicated by former Baltimore Mayor William Donald Schaefer and President Ronald Reagan in October 1984.

Soon after, Pica, who also has served as a Maryland state senator, said his group hired divers to fish pieces of the statue out of the harbor. They raised money through grants and private contributions to hire a Maryland sculptor to rebuild it, Pica said.

The replica had been finished for a few years and sat in storage until Pica got a call last week that the White House wanted the statue. The statue was installed around 2 a.m. Sunday morning, he said, and it is on loan to the White House until the end of Trump’s term.

“It’s a place where it can peacefully shine and be protected,” he added.

“It’s a source of pride for Italian Americans,” Pica said. “Christopher Columbus, notwithstanding the controversy around him, is a symbol of pride and adventure for Italian Americans.”

Pica said he understands the hesitancy around Columbus’ legacy. In a way, he said, Italian Americans are “stuck” with Columbus.

“We don’t raise a glass of wine to Christopher Columbus on Columbus Day,” Pica said. “We celebrate our heritage. We don’t have Columbus celebrations. We have Italian American celebrations and Italian heritage celebrations. It’s just Columbus happens to be the symbol.”

The statue is not the administration’s first attempt to shine a favorable light on the controversial figure.

Last year, the Trump administration issued a proclamation commemorating Columbus Day, and took a jab at people who have criticized the explorer.

“Outrageously, in recent years, Christopher Columbus has been a prime target of a vicious and merciless campaign to erase our history, slander our heroes, and attack our heritage,” the proclamation read. “Before our very eyes, left-wing radicals toppled his statues, vandalized his monuments, tarnished his character, and sought to exile him from our public spaces.”

Indigenous Peoples’ Day, which is not an official federal holiday but is celebrated by cities and states across the country, previously had been recognized by the Biden administration.

Members of the public offer mixed reactions to the statue

On Monday morning, groups of schoolchildren, tourists and locals passed by the White House and offered differing opinions of the statue.

The statue wasn’t visible to the public because of construction and fences walling off the area. But when Ivone Sagastume, a first-generation Guatemalan American, heard about the new statue, she was brought to tears. To her, she said, the statue is another way the Trump administration is dividing the country.

“We as a nation have fought for unity and for respect of other cultures,” Sagastume, 35, said. “That symbol is just going to destroy that even more, it’s just destroying what this country was built on.”

Gerald Horne, a professor of history and African American studies at the University of Houston, said that reaction to the statue makes sense.

“Statues are political statements and those who have objected to the statue of Christopher Columbus are objecting to his role in helping to ignite genocide against the Indigenous population, of being an enslaver himself,” Horne said.

Middle school history teacher Scott Silk, 57, looked out at the White House with a group of students from San Diego behind him.

“For so many people in the United States, Christopher Columbus is a symbol of racism and the oppression of native peoples,” he said.

He said if he and his students could see the statue, he would ask them to reflect on what it means.

But others, like Martha Castillo, a tourist from San Diego, Calif., said it’s important to remember American history.

“I think it’s a good idea to have it here,” Castillo, 55, said. “This is a historic place and I think it should be here in the White House.”

Peter Diaz, 47, traveled from Miami, Fla. to explore the city’s capital. Diaz said the country has “bigger problems” than a statue.

“How many statues do we have in every city? In every state?” he said. “Are those really the issues that we care about? Don’t you think we have to think about our kids?”

Travelers are facing long waits at airport security checkpoints as the partial government shutdown continues to strain staffing for Transportation Security Administration workers. About 50,000 T.S.A. personnel have been working without pay for over a month, and hundreds have quit or called out of work.

On Monday, President Trump deployed Immigration and Customs Enforcement agents to some U.S. airports, saying that they would help ease long security lines. By Monday afternoon, the lines at the Atlanta, LaGuardia and Newark airports had become so long that those airports removed wait time estimates from their websites. Atlanta’s airport advised passengers to allow for at least four hours for security screenings.

Here are the latest available wait times at select major airports across the country.
