Air traffic controllers lost communication for about 10 minutes with a small Mexican Navy plane carrying a young medical patient and seven others before it crashed off the Texas coast, killing at least five people, Mexico’s president said Tuesday.

Authorities initially believed the plane had landed safely at its destination in Galveston, near Houston, before learning it had gone down Monday afternoon, Mexican President Claudia Sheinbaum said. The cause of the crash remains under investigation. A search-and-resuce operation in waters near Galveston pulled two survivors from the plane’s wreckage, Mexico’s Navy said, while one remained missing.

Four of the eight people aboard were Navy officers and four were civilians, including a child, Mexico’s Navy said. Two of the passengers were affiliated with a nonprofit that helps transport Mexican children with severe burns to a hospital in Galveston.

“My condolences to the families of the sailors who unfortunately died in this accident and to the people who were traveling on board,” Sheinbaum said in her morning press briefing, without elaborating on a possible cause. “What happened is very tragic.”

U.S. Coast Guard Petty Officer Luke Baker said at least five aboard had died but did not identify which passengers.

The plane crashed Monday afternoon in a bay near the base of the causeway connecting Galveston Island to the mainland. Emergency responders rushed to the scene near the popular beach destination about 50 miles (80 kilometers) southeast of Houston.

Sky Decker, a professional yacht captain who lives about a mile (1.6 kilometers) from the crash site, said he jumped in his boat to see if he could help. He picked up two police officers who guided him through thick fog to a nearly submerged plane. Decker jumped into the water and found a badly injured woman trapped beneath chairs and other debris.

“I couldn’t believe. She had maybe 3 inches of air gap to breathe in,” he said. “And there was jet fuel in there mixed with the water, fumes real bad. She was really fighting for her life.”

He said he also pulled out a man seated in front of her who had already died. Both were wearing civilian clothes.

It’s not immediately clear if weather was a factor. The area has been experiencing foggy conditions over the past few days, according to Cameron Batiste, a National Weather Service meteorologist. He said that at about 2:30 p.m. Monday a fog came in that had about a half-mile visibility.

Mexico’s Navy said the plane was helping with a medical mission in coordination with the Michou and Mau Foundation. In a social media post, the foundation said: “We express our deepest solidarity with the families in light of these events. We share their grief with respect and compassion, honoring their memory and reaffirming our commitment to providing humane, sensitive, and dignified care to children with burns.”

Teams from the Federal Aviation Administration and National Transportation Safety Board were at the crash site Monday, the Texas Department of Public Safety said, and a spokesperson for the NTSB said the agency was gathering information about the crash. The Galveston County Sheriff’s Office said officials from its dive team, crime scene unit, drone unit and patrol responded the crash.

A small Mexican Navy plane transporting a 1-year-old medical patient along with seven others crashed Monday near Galveston, killing at least two people, officials said.

Emergency officials rescued four people and were searching for two that were inside the aircraft, Mexico’s Navy said in a statement to The Associated Press. Four of the people aboard were Navy officers and four were civilians, according to the Navy. It was not immediately clear which ones were missing and which had been killed.

Two of the people aboard were members from the Michou and Mau Foundation, which is a nonprofit that provides aid to Mexican children who have suffered severe burns.

The crash took place Monday near the base of a causeway near Galveston, along the Texas coast about 50 miles southeast of Houston.

Mexico’s Navy said in a statement that the plane was helping with a medical mission and had an “accident.” It promised to investigate the cause of the crash.

The Navy is helping local authorities with the search and rescue operation, it said in a post on the social media platform X.

Teams from the Federal Aviation Administration and National Transportation Safety Board have arrived at the scene of the crash, the Texas Department of Public Safety said on X.

The Galveston County Sheriff’s Office said officials from its dive team, crime scene unit, drone unit and patrol were responding to the crash.

“The incident remains under investigation, and additional information will be released as it becomes available,” the sheriff’s office said in a post on Facebook, adding that the public should avoid the area so emergency responders can work safely.

Galveston is an island that is a popular beach destination.

It’s not immediately clear if weather was a factor. However, the area has been experiencing foggy conditions over the past few days, according to Cameron Batiste, a National Weather Service meteorologist.

As the holiday season continues, at CBS News Texas, we are once again proud to honor those making a difference in our community.    

As part of CBS News Texas’ third annual 11 Days of Giving campaign, supported by Tom Thumb Albertsons, $1,000 is awarded each day to a local nonprofit making a meaningful impact.

Today, we’re introduced to 4-Legged Helpers, a non-profit helping local animal shelters keep animals safe, fed, and prevent them from being euthanized all over the Dallas-Fort Worth Metroplex.

One of those animals is Bosco.

“He’s a big old goofball,” said Carlos Renovato.  

Bosco is also looking for a home. Renovato is the animal control officer in Wilmer, and he said it’s a struggle to provide for the animals he’s tasked with caring for.  

“Our budget’s not enough for the resources; if an emergency comes along, they don’t have the ability to go to the vet or the funds to feed them. So, it comes down to euthanizing the dogs,” said Renovato. 

Luckily, for Renovato and Bosco, they know Heather Marks and Leanne Hayden.  

“We donate, we help him with food, toys, treats, things like that, if there’s anything he needs, we’ll just let him know and make sure he gets it,” said Marks. 

The two founded 4-Legged Helpers.

“The animals just need help,” said Marks. 

They estimate it costs around $700 per animal to get them adoption-ready.  

“That’s a lot, but it’s worth it. Because they wouldn’t see tomorrow if we didn’t step in,” said Marks. 

That’s why 4-Legged Helpers was selected to receive a $1,000 donation. The money will keep goofballs like Bosco happy and healthy.  

“We are their voice, and if we weren’t here to fight for them, no one would be,” said Marks.
