United States Coast Guard crews are searching waters off Nantucket for a small jet that disappeared while travelling from Bermuda to Boston, according to US media reports.

The aircraft departed Bermuda bound for Boston but failed to arrive as expected, prompting an air and sea search in the Atlantic south of New England. Details on the number of people aboard and the circumstances of the disappearance had not been confirmed at the time of publication.

The route between Bermuda and Boston is one of the island's busiest air corridors, used year-round by residents, business travellers and visitors. Any incident involving a Bermuda-departing flight is likely to raise concern locally, where the aviation and marine communities are closely connected to operations at LF Wade International Airport.

Bermuda's own emergency services have long experience coordinating with the US Coast Guard on search and rescue operations, as the island sits roughly 650 miles east-southeast of Cape Hatteras and ocean crossings are a routine part of life. Authorities are expected to release further information as the search progresses. The Bermuda Observer will provide updates as confirmed details become available.
