Five people were killed after a small aircraft belonging to the Mexican Navy crashed into the water off Galveston, Texas, on Monday, officials said. The Mexican Navy said eight people were on board: five died, two were rescued alive, and one person remained missing as search efforts continued.
The crash occurred after 3 p.m. near Galveston along the Texas coast, about 50 miles southeast of Houston. Officials said the cause was not immediately known and remains under investigation.
A medical transport mission, officials say
Mexican Navy officials said the aircraft was conducting a humanitarian mission focused on specialized medical transport. U.S. and Mexican reporting on the incident described the flight as part of a cross-border effort to move a medical patient for treatment in Texas.
The Associated Press reported the aircraft was transporting a young medical patient and was headed toward care in Galveston. The Washington Post and regional outlets also reported that the mission involved a nonprofit organization that helps Mexican children with severe burn injuries access specialized treatment.
Authorities have not publicly identified the patient, the survivors, or the missing person.

Where the crash happened and what responders faced
Officials said the aircraft went down in or near Galveston Bay, close to the causeway that links Galveston Island to the Texas mainland. Local and federal responders launched a water rescue operation shortly after the crash was reported.
The response included multiple agencies, with reports citing the U.S. Coast Guard among the search-and-rescue units working the scene. Some accounts also noted challenging conditions on the water, including fog and low visibility in the area around the time of the crash.
As with many water crashes, the early hours were focused on locating survivors and accounting for everyone on board. Recovery and investigative work typically begin in parallel once the immediate rescue phase stabilizes.
Casualty numbers and what is confirmed
The Mexican Navy’s statement said five people died, two people were alive, and one person was still missing. Officials said the survivors and injured were transported for evaluation, while the search continued for the missing passenger.
Some early local reporting differed on the initial counts as responders worked in real time, but official figures from Mexican authorities described five fatalities and one person unaccounted for.
Officials have not said whether the missing person was believed to be trapped in the aircraft, swept away from the crash site, or located elsewhere in the bay.
Who was on board, according to the reporting
Authorities have not released the names of the victims or survivors. However, reporting by the Associated Press said the flight included both Mexican Navy personnel and civilians.
The Washington Post reported the aircraft carried four military personnel and four civilians. Multiple outlets reported that the civilian passengers included people connected to the Michou y Mau Foundation, a Mexican nonprofit involved in arranging specialized burn care for children.
Officials have not confirmed the specific roles of each person on board beyond describing the flight as a medical transport mission.
What investigators will examine
The cause of the crash remained unclear Monday night and Tuesday morning. Reporting on the incident said federal aviation safety authorities were collecting information, as is typical in U.S. aviation accidents, alongside coordination with Mexican officials given the aircraft’s ownership and crew.
Investigators generally focus first on basic elements of the flight: the aircraft’s route, communications, weather, maintenance history, and any evidence recovered from the wreckage. If the plane carried tracking equipment, that data can help reconstruct altitude, speed, and heading in the moments before impact.
Weather can be a factor in coastal and bay-area flights, particularly when visibility drops quickly. While some reporting noted fog in the area, officials have not said whether weather contributed.
A rare cross-border crash response
Military aircraft from Mexico do not frequently appear in U.S. incident logs, but cross-border coordination can occur in humanitarian cases involving medical transport. In this case, officials said the purpose of the flight was specialized care, which reporting described as linked to pediatric burn treatment in Galveston.
The crash drew attention because it combined three high-stakes elements: an international military aircraft, a medical transport mission, and an accident in open water that required immediate multi-agency response.
What comes next
Authorities said further updates would depend on two parallel efforts: the ongoing search for the missing person and the investigation into the crash. In many aviation cases, agencies release only limited details early while they gather evidence and interview witnesses.
If the wreckage is recovered, investigators can assess damage patterns and mechanical components to help determine whether the aircraft experienced a failure before impact. Officials have not provided an estimated timeline for preliminary findings.
