Technical Advances At the instigation of Howard Hughes in 1939, Lockheed developed the graceful and powerful Constellation: a pressurized aircraft with nonstop transcontinental capability. The "Connie" was designated by Lockheed as the Model 49, and delivered to the U.S. Army Air Force at the end of World War II as military C-69s. Model 649 was the first Connie intended solely for civilian service. The -649A added reinforced wing panels and heavier landing gear. It could carry 4,000 pounds more payload than the original -49 model. Model 749, first delivered in June 1947, could carry 8,000 pounds over the -49, allowing 40 more passengers or several hundred miles of range. Model 749A could carry a payload of 107,000 pounds.
The speedpak was a removable container which incorporated an electronic winch, attached to the underside of the fuselage. It could be raised or lowered in approximately one minute. The speedpak offered additional bag and cargo space and was easily accessible for cargo loading. Shown here is a Delta-C&S Lockheed Constellation 649A in 1953, with a view of the speedpak underneath the plane. First Delta Connies In the late 1940s, Delta considered the Lockheed Constellation, but decided instead to purchase the Douglas DC-6, which was similar in speed and range, but lower in cost and had a roomer cockpit that only required the customary two pilots, while the Connie required three crew members–pilot, co-pilot and flight engineer. Delta acquired its first Connies–five Model 649As and one Model 749A–from the merger with C&S, effective May 1, 1953. Delta converted the Model 649As to Model 749As, and by June 1954, had leased or sold all the former C&S Connies. Delta Flies Models -49 & -149 In 1956, Delta purchased four early Connies from Pan Am to quickly launch new service from the South to New York City. All were built as Model 49, but two had been upgraded to Model 149. These Connies were withdrawn from Delta service by July 1958, and sold to American Flyers in April 1960. Pics & Video
