British South American Airways' Tudor IV Star Tiger disappears over the Bermuda Triangle.

British South American Airways (BSAA) was a state-run airline of the United Kingdom in the mid-to-late 1940s responsible for services to the Caribbean and South America. Originally named British Latin American Air Lines, it was renamed before services started in 1946. BSAA operated mostly Avro aircraft: Yorks, Lancastrians and Tudors and flew to Bermuda, the West Indies, Mexico and the western coast of South America. After two high-profile aircraft disappearances it was merged into the British Overseas Airways Corporation at the end of 1949.

Star Tiger was an Avro Tudor IV passenger aircraft owned and operated by British South American Airways (BSAA) which disappeared without a trace over the Atlantic Ocean while on a flight between Santa Maria in the Azores and Bermuda in the early morning of 30 January 1948. The loss of the aircraft, along with that of BSAA Avro Tudor Star Ariel in 1949, remains unsolved, with the resulting speculation helping to develop the Bermuda Triangle legend.

The Bermuda Triangle, also known as the Devil's Triangle, is a loosely defined region in the North Atlantic Ocean, roughly bounded by Florida, Bermuda, and Puerto Rico. Since the mid-20th century, it has been the focus of an urban legend suggesting that many aircraft, ships, and people have disappeared there under mysterious circumstances. However, extensive investigations by reputable sources, including the U.S. government and scientific organizations, have found no evidence of unusual activity, attributing reported incidents to natural phenomena, human error, and misinterpretation.
