Star Tiger and Star Ariel
UnsolvedSummary
Two Avro Tudor IV airliners of British South American Airways vanished almost a year apart on flights to and from Bermuda, with 31 people in 1948 and 20 in 1949. Neither sent a distress call, and no wreckage of either has ever been found.
A Court of Investigation under Lord Macmillan examined the loss of Star Tiger and concluded that her fate "must remain an unsolved mystery". The Chief Inspector of Accidents found the cause of Star Ariel's loss unknown, for lack of wreckage. The two flights had little in common beyond the aircraft type, the airline and the island: one was last heard from at night, near the end of a long crossing planned at 2,000 feet, the other at 18,000 feet in good weather, an hour after take-off.
What is documented
The aircraft. Both were Avro Tudor IVs of the state-owned British South American Airways Corporation (BSAA). Star Tiger was registered G-AHNP. Star Ariel, a Tudor IVB, was registered G-AGRE.
Star Tiger's crossing. Star Tiger left London on 27 January 1948 on a scheduled service to the Caribbean by way of Lisbon, the Azores and Bermuda. On the first stage the cabin heating failed and one of the compasses gave trouble. She carried six crew under Captain Brian McMillan and 25 passengers, among them Air Marshal Sir Arthur Coningham, recently retired from the Royal Air Force. Bad weather turned the stop in the Azores into an overnight stay. At 3.34 pm GMT on 29 January she left Santa Maria for Bermuda, about 1,960 nautical miles away, 72 minutes behind a BSAA Lancastrian on the same route. The crews planned to fly at 2,000 feet throughout, the height that offered the least adverse wind. An engineer told the court that the captain had asked him to "fill her up to the gills".
The winds. The winds through the night were stronger than forecast. At 1.26 am the Lancastrian's navigator found from a star fix that a wind he put at 48 knots had carried his aircraft about 68 miles north of track in an hour; the Bermuda forecasts had given 20 to 25 knots. By 3 am Star Tiger had put back her expected arrival from 3.56 am to 5 am; on her own figures, the court calculated, it should have been about 5.30 am. Her hourly reports gave her height as 20,000 feet, which the court took to be an error for 2,000; her actual height when contact ceased could not be established.
The last signal. At 3.04 am Star Tiger's radio officer asked the Bermuda radio station for a bearing, which could not be obtained. At 3.15 am he asked again, received a bearing of 72 degrees, and acknowledged it. That was the last signal heard from the aircraft. She was then about 340 nautical miles from Bermuda, on the approach from the east-north-east. The court found the weather in her area stable, with no serious disturbance and no electrical storms. No distress message was heard by any station. The Lancastrian landed at Kindley Field at 4.11 am. The Bermuda operator called Star Tiger at 3.50 am, 4.05 am and 4.40 am without reply, and declared an emergency 95 minutes after the last contact. The United States authorities who ran the airport organised a search. No trace of the aircraft or of the 31 people aboard was found.
The Macmillan inquiry. A Court of Investigation under Lord Macmillan sat in public at Church House, Westminster, from 12 April 1948. Its report was published in September 1948 as Command Paper 7517. It found that the Bermuda radio station had twice let contact lapse for longer than the 30 minutes its instructions allowed (55 and 42 minutes), and criticised the operator for waiting 95 minutes after the last signal before declaring an emergency. On the cause it could say only that "the Court has not been able to do more than suggest possibilities, none of which reaches the level even of probability." Its conclusion: "What happened in this case will never be known, and the fate of Star Tiger must remain an unsolved mystery."
Star Ariel. On the morning of Monday 17 January 1949 Star Ariel left Kindley Field for Kingston, Jamaica, under Captain J. C. McPhee. The minister told Parliament that she carried 13 passengers and seven crew; Flight's report at the time named six crew. The flight was planned at 18,000 feet, with an estimated flight time of 5 hours 25 minutes, and the forecast of good weather along the route was later confirmed. The Chief Inspector of Accidents' report, as summarised by Flight, puts her departure at 12.42 pm GMT with fuel for ten hours (Flight's first report had given 12.25 pm and eleven hours). She passed a routine position report at 1.37 pm GMT, and at 1.42 pm sent her last message: her radio operator was changing to the Kingston frequency. Nothing more was heard. BSAA aircraft and United States forces searched without result.
The consequences. BSAA suspended its Tudor IVs pending an examination of each aircraft, and the minister asked Lord Brabazon to inquire into the type's design and construction. By March 1949 it had been announced that the Tudor IV would carry freight only. The Chief Inspector's report, published in December 1949, found that all safety conditions had been met, that there were no weather complications and no evidence of sabotage, and that in the absence of wreckage the cause of the accident was unknown.
How the pairing began. Flight's editorial of 27 January 1949 noted that once again a BSAA Tudor "has disappeared without trace" and that "Bermuda is the common denominator in the two cases of vanishing aircraft". In March 1949 the magazine observed that the two Tudors had been lost "in an area where several American aircraft have disappeared". The area was given a name in the 1960s, and both losses became standard entries in Bermuda Triangle books (see AR-0014).
Leading explanations
A sudden failure that left no time for a distress call (consistent with both losses; untested). Neither aircraft sent a distress message, although many stations would have been listening on Star Tiger's frequency. Flight's editorial of January 1949 reasoned that whatever overtook Star Ariel allowed "no chance for the radio operator to send out any signal". Without wreckage, no particular failure can be tested.
For Star Tiger, the conditions of the crossing (documented factors; not established as a cause). The court drew attention to the low height, which left less opportunity to deal with any emergency, to forecasts that underestimated the wind, and to the lapses at the Bermuda radio station. It did not find that any of them caused the loss.
Sabotage (raised at the time; no evidence found). Flight's editorial on Star Ariel listed sabotage among conceivable causes, with an airscrew failure and severe weather, and called it "not a very likely explanation". The Chief Inspector found no evidence of sabotage.
Anything anomalous (no evidence). Nothing in either record requires it. The region does not lose ships or aircraft at an unusual rate (see AR-0014), and Star Tiger was last heard from outside it.
What the popular version gets wrong
"Both airliners vanished in the Bermuda Triangle." Star Tiger was last heard from well outside it. Her last signal placed her about 340 nautical miles from Bermuda, on a bearing of 72 degrees, still on the approach from the Azores. The triangle as usually drawn runs from Bermuda south and west to Puerto Rico and Miami, so her last known position and her route to the island lay outside it. Star Ariel, an hour out on a south-westerly course for Jamaica, was last heard from inside it.
"Even the official inquiry could not explain it." The court could not choose between possibilities because it had nothing to examine: no wreckage, no survivors, no distress message. Its "unsolved mystery" was a statement about missing evidence, in a report otherwise concerned with forecast winds, fuel and the keeping of a radio watch. The Star Ariel report said the same more plainly.
"Both aircraft were at the limit of their range." Fuel is a fair question for Star Tiger, running an hour late near the end of a 1,960-nautical-mile crossing into winds stronger than forecast. It is not a question for Star Ariel, which carried fuel for at least ten hours on a flight planned at five hours twenty-five minutes, and was last heard from an hour after take-off.
Current status
Unsolved. Both inquiries reached the only finding the evidence allowed: the cause is unknown. Nothing from either aircraft has been recovered, and the registry has found no later official reinvestigation of either loss. Wreckage identified as one of the two aircraft would be the first new evidence since 1949.
