The loss of Star Tiger
The airliner Star Tiger vanished over the Atlantic in the early hours of 30 January 1948, travelling between the Azores and Bermuda.
Star Tiger was an Avro Tudor passenger aircraft, registration G-AHNP, run by British South American Airways. Wikipedia records that it vanished without trace over the Atlantic Ocean, on the route from Santa Maria, in the Azores, to Bermuda, around dawn on 30 January 1948. The Times, in a 1996 article, set the departure the night before.
The Ministry of Civil Aviation held a Court investigation into the accident under air navigation regulations dating from 1922, and published a report. The Times wrote in 1996 that wreckage was never found, so the reason it vanished will probably remain unknown. Wikipedia says the loss of Star Tiger, together with that of the Tudor Star Ariel in 1949, remains unsolved.
The Royal Gazette of Bermuda says the unexplained disappearances of these two airliners, Star Tiger in 1948 and Star Ariel in 1949, largely account for the Bermuda Triangle's name.
"Star Tiger (registration G-AHNP) was an Avro Tudor 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."
