The Star Tiger and the Star Ariel

On the thirtieth of January, 1948, a British passenger airliner approaching Bermuda from the Azores stopped responding to its radio forty minutes before landing. Thirty-one people were aboard. No distress signal. No mayday. No wreckage was ever found.On the seventeenth of January, 1949 — almost exactly one year later — the airliner's sister ship, the same model from the same fleet on the same route, made one routine position report south of Bermuda and then went silent. Twenty people aboard. Again no wreckage. Again no answer.The official inquiries into both losses returned the same verdict: "Through lack of evidence, the cause of the accident is unknown." It was the founding event of what newspapers would later call the Bermuda Triangle.This is the story of the Star Tiger and the Star Ariel. The Avro Tudor that briefly looked like the future of British aviation. The cabin heater design flaw quietly identified decades later. And the question of whether the two disappearances were the same accident, twice — or two completely different mysteries that happened to share an airline and an ocean.Episode Thirteen of The Quiet Files.Sources: Star Tiger Court of Inquiry Report (UK Air Ministry, August 1948); Star Ariel Court of Inquiry Report (UK Air Ministry, December 1949); Tom Mangold, Tiger in the Atlantic: The Aviation Mystery of the Star Tiger (2004); subsequent Air Accidents Investigation Branch reviews.
