The US Coast Guard is searching the Atlantic south of Nantucket, Massachusetts, for an air ambulance jet carrying six people that lost contact with air traffic control early Saturday, October 3. The Gulfstream G100 was flying from Bermuda to Boston after a medical evacuation mission. As of mid-morning, no debris or survivors had been publicly reported, and officials had not named the people on board.
The Federal Aviation Administration lost contact with the aircraft early Saturday and issued a Search and Rescue alert at about 1:20 a.m., according to FAA spokesperson Rick Breitenfeldt. The Coast Guard’s Northeast District announced the search on X at about 6:15 a.m. and said air and surface crews had launched.
What officials have confirmed
The aircraft is a Gulfstream G100 with Canadian registration C-GRJP. Latitude Air Ambulance, a company based in Hamilton, Ontario, operates it. The jet left L.F. Wade International Airport in Bermuda at 11:41 p.m. ET on Friday, according to flight-tracking data. It was due to land at Boston Logan International Airport at about 1:25 a.m. Saturday.
The Boston Globe reported that four crew members and two passengers were on board. Latitude says its air ambulance flights typically carry two pilots, a nurse and a respiratory therapist, and sometimes a physician. Officials have not said whether a patient was on the flight, and nobody has released the identities of those aboard. The Coast Guard said it is working with the FAA and the agency’s Rescue Coordination Center.
The Coast Guard said the search area lies off the coast of Nantucket. The Nantucket Current reported that the search began about 13 nautical miles south of the island.
What the flight data shows
Public flight-tracking records list the aircraft under the call sign HTT104, according to the New Bedford Guide. The same records show the jet flew from Bermuda to Boston in June 2025, so the route is one this aircraft has flown before.
Here is the timeline as reported so far. The jet left Bermuda at 11:41 p.m. ET Friday. The altitude drop came shortly after 1 a.m. The FAA issued its alert at about 1:20 a.m. The scheduled landing was about 1:25 a.m. The Coast Guard posted about the search at about 6:15 a.m., and the search was still under way at 10 a.m., Boston.com reported.
FlightAware data showed the plane dropping from roughly 25,000 feet to about 11,000 feet shortly after 1 a.m., according to the Daily Mail’s reporting. CBS News reported that the aircraft lost contact after about one hour and 45 minutes in the air. The Daily Mail said the final ping came at around 1:30 a.m., shortly before the scheduled landing.
The exact times differ between reports, and neither the FAA nor the Coast Guard has described what happened to the plane. Investigators have not given a cause, and nothing in the public record yet explains the drop in altitude.
NBC News obtained air traffic control audio from Boston that appears to show controllers asking the aircraft whether it was “coming in blind.” Authorities have not commented on it.
Who is searching
Several Coast Guard units are on scene. The service said crews from Air Station Cape Cod, Station Brant Point on Nantucket and the cutter William Sparling are responding. Boston 25 News reported that the air assets include an HC-144 Ocean Sentry fixed-wing aircraft and an MH-60 Jayhawk helicopter from Air Station Cape Cod. Master Chief John Lowell told the Nantucket Current that the Brant Point station’s 47-foot motor lifeboat was already in the search area.
The Coast Guard said it will post updates as information becomes available. The FAA is coordinating with the Coast Guard to locate the aircraft.
At Boston Logan, Massachusetts Port Authority Fire Rescue began staging to meet the plane, which did not arrive, Massport spokesperson Jennifer Mehigan told the Globe. Massport confirmed the jet did not land as scheduled.
What Latitude Air Ambulance has said
Clarence Togeretz, Latitude’s director of flight operations, told NBC News that the crew was carrying out a medical evacuation in Bermuda. He said Latitude has an emergency response plan “absolutely for anything that might occur to any of our missions.”
Togeretz acknowledged the company’s concern. He said Latitude gets worried when a crew “doesn’t report to us in a timely manner.” He also said he was staying hopeful. In his words, the delay “doesn’t mean that the worst has happened.”
The company had not issued a fuller statement when these reports were published. The Daily Mail said it had contacted both Latitude and the Coast Guard for comment.
About the company and the aircraft
Latitude launched in 2009 and flies patients to hospitals and back to their home countries. The Daily Mail reported that the Canadian company has a fleet of 10 aircraft, including four Gulfstream G100s. A listing with the European air ambulance accreditation body EURAMI describes a smaller fleet of five aircraft, three of them G100-type jets, so published counts vary by source.
The G100 is a twin-engine business jet originally developed in Israel, and the Daily Wire reported that some are equipped as intensive care transport aircraft. Bermuda is a British overseas territory in the North Atlantic, about 650 miles from North Carolina. The flight path to Boston runs northwest across open ocean and ends near the Massachusetts coast, where the search is concentrated.
What happens next
The Coast Guard has not given an end time for the search. Crews will keep working the area south of Nantucket, and the service has said more information will follow. The reporting available so far does not identify any of the six people on board or their families.
Several questions remain open: who was aboard, whether a patient was on the flight, what caused the loss of contact, and where the aircraft is. No agency has announced an investigation in the coverage available so far.
This is a developing story. The Coast Guard and the FAA are the main sources for confirmed updates.
