A medical evacuation aircraft has gone missing after departing Bermuda on a flight bound for Boston, prompting an urgent search operation across the Atlantic, authorities confirmed.

The aircraft, which was transporting a patient from the island to the United States for treatment, lost contact with air traffic controllers after leaving Bermuda's airspace. Local emergency officials said they are working closely with United States authorities to coordinate search and rescue efforts along the plane's expected flight path over the open ocean.

Medevac flights are a lifeline for Bermuda residents, with patients regularly airlifted to hospitals in Boston and other East Coast cities for specialist care not available on the island. The disappearance has sent shockwaves through the small community, where such flights are a routine and trusted part of the healthcare system.

Officials have not yet released details about how many people were aboard the aircraft, which typically carries a patient, medical crew and pilots. Weather conditions in the region at the time of the flight have not been disclosed, and the cause of the disappearance remains unknown.

Bermuda's emergency services said they would provide updates as more information becomes available. Families with loved ones who travel overseas for medical care have expressed deep concern, and community leaders have called for prayers for those on board. The US Coast Guard is understood to be leading search efforts in international waters, with support from assets in the region.
