Star Ariel was an Avro Tudor Mark IVB 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 Bermuda and Kingston, Jamaica, on 17 January 1949. The loss of the aircraft, along with that of BSAA Avro Tudor Star Tiger in January 1948, remains unsolved, with the resulting speculation helping to develop the Bermuda Triangle legend.
