A Canadian-registered air ambulance with six people on board that departed Bermuda early Saturday morning has disappeared from radar off the coast of Massachusetts, prompting an active search and rescue operation by the U.S. Coast Guard.

The aircraft was en route from Bermuda to Boston when air traffic controllers lost contact early Saturday.

UPDATE — October 3, 2026

Since this report was published, additional information has emerged about the final stages of HTT104’s Bermuda-to-Boston flight.

Flight-tracking data indicates that C-GRJP descended rapidly from approximately 24,000 feet to around 11,000 feet before appearing to level off. The crew also reportedly declared an emergency, with an electrical issue reported before contact with the aircraft was lost.

Flight-tracking records show C-GRJP descended rapidly from approximately 24,000 feet — data that raises questions about the aircraft's final minutes.

Aviation experts are examining the rapid descent and weather conditions along the route, but the official cause of the disappearance has NOT been determined.

Regarding the 15-minute Hamilton flight covered in the video above: flight-tracking records confirm that the aircraft departed Hamilton, Ontario, and returned to Hamilton approximately 15 minutes later on October 1. The purpose of that flight remains unconfirmed. There is currently no established evidence that it was a maintenance/test flight or that it was connected to the later electrical problem.

What Skyport Has Confirmed

Skyport, operator of L.F. Wade International Airport, has confirmed the departure:

A Canadian-registered air ambulance departed L.F. Wade International Airport for Boston at approximately 12:41 a.m. on Saturday, October 3, 2026, with six souls on board, including four crew members and two passengers.

The U.S. Federal Aviation Administration has advised that air traffic controllers subsequently lost contact with the aircraft off the coast of Nantucket Island, Massachusetts, and a search is currently underway. Skyport has no further information to provide at this time.

The 12:41 a.m. departure time reported by Skyport aligns with earlier aviation reports listing the departure as approximately 11:41 p.m. Friday night.

Search Operation

The U.S. Coast Guard says it has deployed both air and surface crews to search for the aircraft. Operations are concentrated in waters south of Nantucket, Massachusetts.

The FAA has advised that contact was lost during the early hours of Saturday. The Coast Guard operation remains an active search and rescue mission.

The Aircraft

Reports identify the aircraft as a Gulfstream G100, a twin-engine business jet, registration C-GRJP. The aircraft in the file photo above shows that registration, with a Canadian flag and air ambulance markings on the tail.

American media and aviation observers are reporting the aircraft was operating as HTT104 on the Bermuda to Boston Logan International Airport route, and is operated by Latitude Air Ambulance, a Hamilton, Ontario-based medical aviation company. Latitude's Director of Flight Operations, Clarence Togeretz, is quoted in those reports as saying the aircraft had been carrying out a medical evacuation in Bermuda.

According to preliminary flight-tracking information cited by aviation observers, the aircraft descended more than 9,000 feet over a period of about 2 minutes. The last data was received approximately 2 minutes later near the current search area. That tracking data has not been confirmed by the FAA or Coast Guard.
