Lady Be Good is a B-24D Liberator bomber that disappeared without a trace on its first combat mission during World War II. The plane, which was from 376th Bomb Group of the United States Army Air Forces (USAAF), was believed to have been lost—with its nine-man crew—in the Mediterranean Sea while returning to its base in Libya following a bombing raid on Naples on April 4, 1943. However, the wreck was accidentally discovered 710 km (440 mi) inland in the Libyan Desert by an oil exploration team from British Petroleum on November 9, 1958. A ground party in March 1959 later identified the aircraft as a B-24D.

The Libyan Desert is a geographical region filling the northeastern Sahara Desert, from eastern Libya to the Western Desert of Egypt and far northwestern Sudan. On medieval maps, its use predates today's Sahara, and parts of the Libyan Desert include the Sahara's most arid and least populated regions; this is chiefly what sets the Libyan Desert apart from the greater Sahara. The consequent absence of grazing, and near absence of waterholes or wells needed to sustain camel caravans, prevented Trans-Saharan trade between Kharga close to the Nile, and Murzuk in the Libyan Fezzan. This obscurity saw the region overlooked by early European explorers, and it was not until the early 20th century and the advent of the motor car before the Libyan Desert started to be fully explored.
