The twentieth century also ushered in the era of air transportation. Airplanes were heavily used in battles between American and Germans in World War I. With the advent of World War II other types of aircraft were also used. Among them was the CG4A glider, a strut based high wing monoplane used to carry men and equipment. Over 1,000 of these gliders were manufactured at the Gibson Refrigerator Company in Greenville in the early 1940s. Greenville children raised about $72,000 to build several gliders one of which, the 'Flying Falcon', was used during the D-Day invasion of Normandy.
