MW116
1945-FEB-01 · Mediterranean Sea, off Lampedusa, Italy

No. 511 Squadron RAF — Flight MW116

An Avro York carrying members of the British delegation to the Yalta Conference ditched in the Mediterranean Sea after the crew became lost and exhausted their fuel supply. The flight was a last-minute replacement for a Liberator that had developed mechanical issues. During the night flight, the crew encountered radio navigation difficulties and out-of-date meteorological forecasts, leading them to circle Lampedusa for over an hour in confusion. By the time they established a correct bearing to Malta, the aircraft lacked sufficient fuel to reach the island.

Report

Investigation Summary

The flight was part of a high-priority transport mission for the 'Big Three' conference at Yalta. The aircraft, MW116, was not the original transport; it was pressed into service when the primary Liberator aircraft suffered an engine fault just before departure. Although the individual crew members were experienced, they had never flown together as a cohesive unit before this urgent mission. After departing England and flying toward the Mediterranean, the weather deteriorated near Naples. The crew intended to divert to Malta, but a combination of radio distortion and navigation errors caused them to miss their destination. They arrived over the island of Lampedusa, which they reportedly failed to identify correctly, circling for approximately one hour. During this time, the wireless operator was working with obsolete weather data and was unable to secure reliable radio bearings. When the crew finally determined their position and the course to Malta, they realized the fuel state was critical. The pilot attempted a ditching in the sea, but the aircraft broke up shortly after impact.

Final Conclusions

The investigation attributed the accident to a series of navigational errors compounded by equipment and operational factors. Key findings included the use of a crew that had not previously trained together, the failure to obtain reliable radio bearings due to distortion, and the reliance on outdated meteorological forecasts. The aircraft remained airborne until fuel exhaustion necessitated a ditching, which resulted in the destruction of the airframe and the loss of 15 lives.
