A medical transport aircraft bound from Bermuda to Boston went missing over the Atlantic on Tuesday, prompting an international search effort led by the U.S. Coast Guard. The single‑engine, 19‑passenger plane, a Cessna 421, departed from Bermuda’s L.F. Wade International Airport at 10:37 a.m. local time, carrying a critically ill patient and a crew of four.

The Bermuda‑based Coast Guard and Federal Aviation Administration have released the names of those aboard: pilot Captain Mark Hines, co‑pilot Lisa Morales, flight nurse Dr. Jacob Thompson, and patient 47‑year‑old Mariah Clarke, who was receiving treatment for a severe neurological condition.

Bermuda’s Ministry of Health announced that the patient was transferred to the island’s only tertiary care facility, the Bermuda Hospital, before departure. Officials confirmed that the patient had been stabilized and the flight was scheduled to facilitate a transfer to Boston’s Massachusetts General Hospital for advanced care.

The search, coordinated by the U.S. Coast Guard’s Atlantic Area Command, covers a 1,500‑mile radius over the open ocean. Bermuda’s aviation authorities are cooperating fully, and the island’s maritime rescue unit has been briefed. The Coast Guard has urged anyone with information to contact the Atlantic Area Command hotline. The incident has highlighted the importance of robust maritime and aviation safety protocols in the Bermuda region.
