The Douglas C-124 Globemaster II, also fondly called "Old Shakey," could carry more than 200 troops. It had clamshell-type loading doors, built-in double hydraulic ramps and an elevator under the aft fuselage. It could load tanks, field guns, bulldozers and trucks. Powered by four 3,800-horsepower Pratt & Whitney R-4360 engines the C-124 could accommodate 5 crew and 200 troops, or 123 litters, or 45 patients with 15 attendants, or 74,000 pounds cargo, with and fly a range of 1,200 miles at 304 mph. Deliveries of the C-124A Globemaster II began in May 1950, and before production ended in 1955, the U.S. Air Force bought 448.
