A desperate search for a missing medical evacuation aircraft has taken a troubling turn after the US Coast Guard discovered a debris field off the coast of Nantucket, Massachusetts.

The Gulfstream G100, operated by Canada’s Latitude Air Ambulance, was flying from Bermuda to Boston with six people on board, including four crew members and two passengers.

The aircraft reportedly encountered serious problems during its overnight flight. According to air traffic control audio, the pilot reported electrical issues and declared an emergency as the aircraft approached the Massachusetts coast amid stormy weather.

Flight tracking data indicates that the jet was cruising at approximately 24,000 feet before suddenly descending around 13,000 feet in just two minutes. Shortly afterward, air traffic controllers lost contact with the aircraft.

In a chilling exchange captured in ATC audio, a controller can be heard asking the pilot whether the aircraft was “coming in blind.”

The US Coast Guard deployed air and surface crews to search the waters near Nantucket. A Coast Guard cutter is expected to continue the search overnight and into Sunday.

Canada’s Transport Minister confirmed that four Canadians were aboard, while the other two passengers were Bermudian nationals. Authorities have notified the families of all six people.

Latitude Air Ambulance officials said the aircraft was conducting a medical evacuation mission in Bermuda and expressed concern after losing contact with their crew.

The discovery of the debris field raises serious concerns about the fate of those on board. However, authorities have not yet confirmed the condition or whereabouts of the six occupants.

The search and rescue operation continues as families and colleagues anxiously await answers.

Thoughts are with everyone on board and their loved ones during this extremely difficult time.
