Searchers found a “debris field” off the coast of Nantucket, Massachusetts, from an air ambulance that was carrying six people when it vanished over the Atlantic on Saturday during a flight from Bermuda to Boston, the U.S. Coast Guard said. Four Canadians and two Bermudian nationals were aboa rd, and their next of kin were notified as the search continued, the Coast Guard said in a statement. It added that one of its cutters would keep searching the water overnight and into Sunday. At a press conference on Sunday morning, U.S. Coast Guard Rear Admiral Matthew Lake said they have been searching since 2 a.m. Saturday, using fixed wing aircraft, helicopters, boats and cutters. So far, they have searched over 2,800 square miles over nearly 54 hours. He said they have been keeping next of kin notified of their progress. “Our priority is to locate the six personnel on that aircraft,” he said. “Our thoughts are with the people on board that aircraft, their families, friends and loved ones during this difficult time.” The area around the debris field is about 80-90 feet, officials said, and they are currently working with Massachusetts authorities to get craft out there equipped with sonar to do some detection on the seabed floor. They provided no set timeline for the search, other than to say that they will continue to search and saturate the area until they are confident that any survivors in the area would have been found. According to the Coast Guard, the Federal Aviation Administration reported that the Gulfstream G100 lost contact very early Saturday morning. Air traffic audio indicates that it may have been “coming in blind” when a storm loomed ahead shortly before it vanished. The pilot reported electrical problems and declared an emergency as the jet approached the coast, according to air traffic control audio posted by LiveATC.net. “Roger, you said you’re coming in blind. Is that what you said?” a controller can be heard asking the pilot. That makes Mary Schiavo, who is a former Inspector General of the Transportation Department, think the plane may have lost its navigational instruments just as a storm moved across its path on radar. The plane also descended sharply from its cruising altitude of around 24,000 feet to around 10,000 feet, according to preliminary data from flight tracking site FlightRadar24. “Something bad happened with this big drop, and they flew into this big storm. It’s a terrible place to have a loss of your instruments and be flying blind,” said Schiavo, who is an aviation attorney. “It’s very easy to get disoriented and not know if you’re turning, climbing, descending, etc.” The Canadian-registered air ambulance jet had four crew members and two passengers aboard when it departed Bermuda’s L.F. Wade International Airport for the nighttime flight to Massachusetts, according to a statement from the Bermuda airport’s operator, Skyport. Transport Canada was closely monitoring and working with authorities on search and rescue efforts, the country’s Minister of Transport Steven MacKinnon said on the social platform X. The National Transportation Safety Board said it was gathering information about the situation, but it did not say immediately if it would investigate.
