The US Coast Guard has halted its search for victims of a medical aircraft disaster.

Six persons who were on a medical transport plane that crashed off the coast of Nantucket Island, Massachusetts, are no longer being sought after by the US Coast Guard.

The aircraft was on its way to Boston’s Logan International Airport and was carrying two Bermudans and four Canadians, according to officials.The head of the Coast Guard’s Northeast District, Rear Admiral Matthew Lake, stated in a statement on Sunday that suspending a search is a difficult choice.

The Coast Guard reported that it looked for the passengers and crew on Sunday using aircraft and vessels on the water after discovering debris from a Gulfstream jet heading to Boston from Bermuda late on Saturday.

According to information from the flight tracking website FlightAware, the aircraft, registered to Canadian air medical transport company Latitude Air Ambulance, departed Bermuda on Saturday at 12:41 a.m. (0301 GMT).

An audio tape of Logan’s air traffic controller asking the Gulfstream pilot if he was declaring an emergency was posted by local TV station Boston 25. The pilot did not respond.We must now confront the devastating reality that the four members of our Latitude team, our patient, and the patient’s family escort who were aboard Heartbeat 104 are presumed to have died in light of the information provided by authorities and the conclusion of the search-and-rescue phase,” Latitude said in a statement on Sunday.

Latitude stated that it would collaborate on recovery efforts and the investigation into the cause of the plane’s crash with the Transportation Safety Board of Canada, the US National Transportation Safety Board, and other authorities.
