Bolero movement of air groups
The movement of the assigned air combat groups began in May 1942 with the shipment by fast troopships (usually former ocean liners) of their ground echelons. The movement of their aircraft began in June after the decision was made that the most efficient and rapid buildup could be made by having the groups themselves ferry their planes overseas. Fighters, having only a single crewman and not equipped with proper navigational and communications equipment for trans-oceanic flights, were to be divided into flights of four and escorted by single bombers navigating the route for them.
Three groups were assigned for the first phase of movement: the
An anticipated loss rate of 10% for the first movement did not materialize and instead was 5.2%. The largest loss occurred July 15, 1942, when six P-38s of the 94th Fighter Squadron, 1st Fighter Group, and two B-17s of the 97th Bomb Group, on the Greenland-to-Iceland leg, were forced by weather to attempt to return to Greenland. Running low on fuel, all eight force-landed on the Greenland ice cap. The aircraft, although apparently recoverable, were abandoned after all of their crews had been safely recovered. One of the P-38s, subsequently named Glacier Girl, was recovered from under ice in 1992, and has been restored to flying condition.[1]
By the end of August 1942, the Bolero movement had transferred 386 airplanes: 164 P-38's of the 1st and

By July 1, demands from other theaters had caused a downward revision of the Bolero build-up to a total of 54 groups and 194,332 men. Later that month USAAF Headquarters estimated that by December 31, 1943, the Bolero build-up could have in place 137 groups (approximately half of the entire projected strength of the USAAF), including 74 bomb groups of all types and 31 fighter groups. It estimated that 375,000 airmen would comprise the force, 197,000 in combat units and 178,000 in the service organizations. The estimate proved to be remarkably close, particularly the size of the heavy bomber force, to the actual strength of the combined Eighth and Ninth Air Forces at the time of Operation Overlord.
In London the Bolero Committee drew up plans for the accommodation of 1,147,000 troops, including 137,000 replacements, in the United Kingdom by the end of March 1943. But by the end of July, plans for Sledgehammer had been abandoned and Roundup postponed until 1944 in favor of Operation Torch, an invasion of North Africa to establish a base of operations for the invasion of Southern Europe. The Bolero committee thus found its work limited to providing assistance in the planning for Torch. Buildup plans for the invasion of Europe later became the province of the Overlord planners.
