UPDATE 12:48 p.m.

When a Mexican navy tall ship crashed into the Brooklyn Bridge, it was maneuvering in turbulent waters. The tide had just turned, and a fast current was heading up the East River as a 10 mph wind set in.

While such hazards are easily handled by an experienced captain, mistakes can be costly in the heavily transited New York harbor, where narrow, curvy channels, winds howling off the jagged Manhattan skyline and whirlpool-like eddies can combine to make for difficult passage.

In the case of the 300-foot (90-meter) Cuauhtemoc, two sailors were killed and 19 were injured Saturday when the ship struck the iconic bridge, toppling the vessel's three masts like dominoes as it drifted toward a crowded pier. It’s unknown what caused the collision, and an investigation by the National Transportation Safety Board is likely to take months.

But footage of the collision shot by horrified onlookers show the ship hurtling into the bridge in reverse at full speed, suggesting the captain lost control of the engine. There are also questions about whether a tugboat escort peeled away too soon and should have been rigged to the ship or stayed with it until it headed out to sea. Similar tugboat concerns emerged when a large cargo vessel crashed into a bridge in Baltimore last year.

Sal Mercogliano, a former merchant mariner who has powered multiple ships through the New York harbor, said all those “worst-case scenarios” — the ship’s height, a strong current, heavy wind and the absence of a more controlled tugboat escort — all contributed to the tragedy.

“The prudent thing would’ve been to leave two hours earlier, when the tide was going out. That would’ve been the ideal time," said Mercogliano, who writes a widely followed shipping blog. “But I don’t think they ever envisioned that their engine would’ve propelled them into the bridge.”

Still, he said an even deadlier catastrophe was avoided by the ship’s steel rigging, which prevented the masts from falling into the water, as well as the fact that the crew stayed harnessed in position rather than taking the risk that some members could tumble from a 12-story height as they scrambled down the rat lines.

“You could have had guys strapped in drowning in the river," he said. “This could have been a lot worse.”

The Cuauhtemoc visited New York as part of a 15-nation global goodwill tour and was departing for Iceland when it struck the bridge at around 8:20 p.m., briefly halting traffic atop the span.

UPDATE 9:21 a.m.

Federal transportation officials have launched an investigation into why a Mexican navy tall ship hit the Brooklyn Bridge in a collision that snapped the vessel's three masts, killed two crew members and left some sailors dangling from harnesses high in the air.

The ship known as the Cuauhtemoc was visiting New York on a global goodwill tour when the accident occurred Saturday evening. The vessel could be seen in multiple eyewitness videos traveling swiftly in reverse toward the bridge near the Brooklyn side of the East River. Then its three masts struck the bridge and snapped, one by one, as the ship kept moving.

It was unclear what caused the ship to veer off course. The National Transportation Safety Board announced that it was sending a team to investigate. Investigators were expected to arrive Sunday afternoon.

ORIGINAL 7:49 a.m.

A Mexican navy sailing ship on a global goodwill tour struck the Brooklyn Bridge in New York on Saturday, snapping its three masts, killing two crew members and leaving some sailors dangling from harnesses high in the air waiting for help.

New York City Mayor Eric Adams said the 142-year-old bridge was spared major damage but at least 19 people aboard the ship needed medical treatment.

Two of the four people who suffered serious injuries later died, Adams announced on social media early Sunday.

The cause of the collision was under investigation.

In a scene captured in multiple eyewitness videos, the ship, called the Cuauhtemoc, could be seen traveling swiftly in reverse toward the bridge near the Brooklyn side of the East River. Then, its three masts struck the bridge's span and snapped, one by one, as the ship kept moving.

Videos showed heavy traffic on the span at the time of the 8:20 p.m. collision. No one on the bridge was reported injured.

The vessel, which was flying a giant Mexican flag and had 277 people aboard, then drifted into a pier on the riverbank as onlookers scrambled away.

Sailors could be seen aloft in the rigging on the damaged masts but, remarkably, no one fell into the water, officials said.

Sydney Neidell and Lily Katz told The Associated Press they were sitting outside to watch the sunset when they saw the vessel strike the bridge.

“We saw someone dangling, and I couldn’t tell if it was just blurry or my eyes, and we were able to zoom in on our phone and there was someone dangling from the harness from the top for like at least like 15 minutes before they were able to rescue them,” Katz said.

Just before the collision, Nick Corso, 23, took his phone out to capture the backdrop of the ship and the bridge against a sunset, Instead, he heard what sounded like the loud snapping of a “big twig." Several more snaps followed.

People in his vicinity began running and “pandemonium” erupted aboard the ship, he said. He later saw a handful of people dangling from a mast.

“I didn’t know what to think, I was like, is this a movie?” he said.

The Mexican navy said in a post on the social platform X that the Cuauhtemoc was an academy training vessel. It said a total of 22 people were injured, 19 of whom needed medical treatment.

Mexican President Claudia Sheinbaum regretted the loss of the two crew members.

“Our solidarity and support go out to their families,” Sheinbaum said on X.

The Brooklyn Bridge, which opened in 1883, has a nearly 1,600-foot (490-meter) main span supported by two masonry towers. More than 100,000 vehicles and an estimated 32,000 pedestrians cross every day, according to the city’s transportation department. Its walkway is a major tourist attraction.

Traffic was halted after the collision but was allowed to resume after an inspection, city officials said.

It was unclear what caused the ship to veer off course. New York Police Department Special Operations Chief Wilson Aramboles said the ship had just left a Manhattan pier and was supposed to have been headed out to sea, not toward the bridge.

He said an initial report was that the pilot of the ship had lost power due to a mechanical problem, though officials cautioned that information was preliminary. Videos show a tugboat was close to the Cuauhtemoc at the time of the crash.

The Cuauhtemoc — about 297 feet long and 40 feet wide (90.5 meters long and 12 meters wide), according to the Mexican navy — sailed for the first time in 1982.

The vessel’s main mast has a height of 160 feet (48.9 meters), according to the Mexican government.

As midnight approached, the broken boat was moved slowly up the East River, going under and past the Manhattan Bridge, aided by a series of tugboats, before docking at a pier. Onlookers continued to gather on the waterfront to watch the spectacle.

Each year the Cuauhtemoc sets out at the end of classes at the naval military school to finish cadets' training. This year it left the Mexican port of Acapulco, on the Pacific coast, on April 6, the navy said.

It arrived in New York City on May 13, where visitors were welcome for several days, the Mexican consulate said. The ship was scheduled to visit 22 ports in 15 nations over 254 days, 170 of them at sea.
