A Canadian-registered Gulfstream G100 air ambulance, C-GRJP, lost contact with air traffic control early on Saturday, October 3, 2026, while flying from Bermuda to Boston with six people aboard. The U.S. Coast Guard has since found a debris field off Nantucket that it says is associated with the aircraft.

As of early October 4, the Coast Guard has not said what the debris is, and it says the search for the six people continues.

What is known about the flight

The jet is operated by Latitude Air Ambulance of Hamilton, Ontario. According to a CBC live report, the crew was two pilots and two medical workers, all Canadian, and the passengers were a patient and the patient’s relative.

CBC, citing Flightradar24 data, said the jet left Hamilton at 7:10 p.m. ET on Friday and landed at Bermuda’s L.F. Wade International Airport at 9:28 p.m. It departed Bermuda at 11:41 p.m. ET for Boston Logan, with an estimated arrival of 1:30 a.m.

The FAA issued a search and rescue alert notice at about 1:20 a.m. ET, according to NBC New York. Latitude told CBC it lost contact with the flight at around 1:30 a.m.

Flight tracking cited by CBC shows the jet dropping from 24,000 feet to about 11,000 feet near 1 a.m. before leveling off briefly. NBC New York put the lower figure at around 10,000 feet.

The radio calls

Air traffic control audio, reported by NBC New York and others, has the pilot reporting electrical problems and declaring an emergency as the jet neared the coast. A controller can be heard asking, “you said you’re coming in blind. Is that what you said?”

ABC News reported that the controller had trouble hearing the pilots and asked them to repeat messages, including their altitude, several times. NBC New York gave the flight’s call sign as “Heartbeat 104.”

What “coming in blind” meant is not established. It could describe the loss of instruments, the loss of radios or something else, and only the recorded data and the wreckage can settle it.

Provisional information

No official cause has been given. Everything here comes from Coast Guard and FAA statements as relayed by news outlets, flight tracking data and air traffic control audio, and it may change as investigators work. Some outlets list the registration as C-GJRP, while CBC and Bernews use C-GRJP.

The search and who investigates

The Coast Guard has searched with aircraft and surface vessels, including the fast response cutter William Sparling, and NBC New York reported that about 1,644 square miles had been covered. A Coast Guard spokesperson told CBC the debris was matched to the aircraft using precise information from other agencies, without giving details.

The NTSB said it was gathering information. When a U.S. accident involves a foreign-registered aircraft, the NTSB normally leads and the country of registry is invited to take part, so Canadian involvement would be expected. Canadian officials have said they are monitoring the situation.

The G100 is a twin-engine business jet from Gulfstream. CBC reported that this was one of four G100s registered to Latitude.

The flight was bound for Boston Logan. Nantucket Memorial Airport told CBC it had been informed that the aircraft reportedly declared an emergency before contact was lost.

The Coast Guard planned a briefing at Base Boston at 11 a.m. on Sunday.

By Sunday, NBC Boston reported that the Coast Guard had notified next of kin of the six people aboard, and that Bermuda’s government said it was in contact with the families as well as the agencies coordinating the search.
