The US Coast Guard officially suspended its search on Sunday, 4 October 2026 for the six passengers aboard a medical transport aircraft that crashed off the coast of Nantucket, Massachusetts, after roughly 66 hours of search operations covering 4,445 square miles. The aircraft, a Gulfstream G100 twinjet, disappeared from Federal Aviation Administration (FAA) radar late Saturday while on a flight from Bermuda's L.F. Wade International Airport to Boston Logan International Airport.

How the Search Unfolded

The plane vanished from FAA radar shortly before its scheduled 1:25 am landing in Boston. Debris from the Gulfstream G100 was first spotted floating in the ocean on Saturday evening, prompting an immediate multi-agency search operation. The wreckage was located approximately 32 kilometres off the Nantucket coastline, in waters between 24 and 28 metres deep.

The Coast Guard and its partner agencies combed an area of 4,445 square miles over approximately 66 hours before the decision to stand down was made. Officials described the debris field as extensive, though they did not disclose its precise dimensions.

The Decision to Suspend Operations

Rear Admiral Matthew Lake, Commander of the Northeast District, announced the suspension and acknowledged its difficulty. “Suspending a search is not an easy decision,” he said. “We express our deepest condolences to the families and loved ones affected by the tragedy and our gratitude for our partner agencies who helped support search efforts.”

The tone of the statement implicitly acknowledged that the prospects of finding survivors had effectively ended, though officials stopped short of formally declaring the six aboard dead.

Black Box Search Complicated by Debris Scale

Alongside the search for survivors, crews had also been attempting to locate the aircraft’s flight data recorder, commonly known as the black box. That effort too yielded no results. “In the debris we’ve identified at this point, there is no indication that we found a black box,” Rear Admiral Lake said.

Kastriot Kastrati, search and rescue mission coordinator for the Coast Guard’s Northeast District, explained that the sheer volume and spread of debris made detailed examination extremely challenging. The size of the debris field made it “very difficult to get into the details of what’s there,” he said. The absence of the black box means investigators may face significant hurdles in reconstructing the final moments of the flight.

The Flight and the Aircraft

The Gulfstream G100 is a twin-engine business jet frequently used for medical air transport. The aircraft was operating as a medical transport flight, carrying six people in total. It was en route from Bermuda to Boston when contact was lost. The sudden disappearance from FAA radar — without any reported distress signal — points to a rapid, catastrophic loss of the aircraft, though investigators have not yet formally attributed a cause.

This is the latest in a series of aviation incidents over US coastal waters, and it comes at a time when regulatory scrutiny of smaller medical and charter aircraft operations remains an ongoing concern in the United States. A full investigation by relevant aviation authorities is expected to follow the recovery of any additional debris or flight data equipment.
