On March 24, 2023, an Avro 691 Lancastrian, G-AGLX, a former Royal Air Force (RAF) Lancaster bomber, experienced a missing aircraft event during a flight from the United Kingdom to Australia. The aircraft departed Colombo’s Negombo RAF Station, Sri Lanka, delayed by two hours due to radio equipment faults. After crossing the Indian Ocean to the Cocos Islands, the crew radioed position reports. The last reported position was approximately 18:00 Perth time, north of the Cocos Islands, within the inter-tropical region where weather conditions were likely unfavorable. An extensive search was unsuccessful, and a faint radio signal was detected by a R.A.F. Liberator based on the Cocos Islands, suggesting a potential distress signal. The crew consisted of Capt.

Description

The Avro 691 Lancastrian operated on a flight from the United Kingdom to Australia. The initial stages to Karachi were carried out by BOAC. The continuing legs from Karachi to Colombo, Cocos Islands, Perth, Gawler and Sydney were carried out by Qantas. Lancastrian G-AGLX was a former RAF Lancaster bomber, converted for civilian use. Reportedly the departure from Colombo’s Negombo RAF Station was delayed for two hours because of a fault in the plane’s radio equipment. After departing for the flight across the Indian Ocean to the Cocos Islands, the crew radioed position reports. The last position report received was at 18:00 hours Perth time. The scheduled report at 18:30 was never received and the aircraft was reported missing. The point at which the Lancastrian last reported, north of Cocos Islands was within the inter-tropic area where the weather front was probably at its worst over the whole route. An extensive search failed to find a trace of the aircraft, even a ? faint undecipher- able signal, such as could have originated from a dinghy transmitter”, was picked up by a searching R.A.F. Liberator based on the Cocos Islands, shortly before dusk on March 24. The Qantas crew consisted of Capt. Thomas First Officer McClelland, Navigating Officer Nuske, Radio Officer McBean, Flight Steward Porteous, and the passengers: Mr. J. Dobson. Mr. J. Knight, Mr. H. Marshland, Mr. J. H. Vose, Mr. H. E. Witteyi
