The C-82 Packet is a twin-engine, twin-boom cargo aircraft designed and built by Fairchild Aircraft. It was used briefly by the United States Army Air Forces and the successor United States Air Force following World War II. 223 units were built. Developed by Fairchild, the C-82 was intended as a heavy-lift cargo aircraft to succeed prewar civilian designs like the Curtiss C-46 Commando and Douglas C-47 Dakota using non-critical materials in its construction, primarily plywood and steel, so as not to compete with the production of combat aircraft. However, by early 1943 changes in specifications resulted in plans for an all-metal aircraft. The aircraft was designed for a number of roles, including cargo carrier, troop transport, parachute drop, medical evacuation, and glider towing. It featured a rear-loading ramp with wide doors and an empennage set 14 feet (4.3 m) off the ground that permitted trucks and trailers to back up to the doors without obstruction. The single prototype first flew on 10 September 1944. The aircraft were built at the Fairchild factory in Hagerstown, Maryland, with deliveries beginning in 1945 and ending in September 1948. Problems surfaced almost immediately. The aircraft was found to be underpowered and its airframe inadequate for the heavy lifting it was intended to perform. As a result, the Air Force turned to Fairchild for a solution to the C-82's shortcomings. A redesign was quickly performed under the designation XC-82B, which would overcome all of the C-82A's initial problems. The C-82A was first flown in 1944, with its initial delivery not until June 1945; as a result, only a few entered service before the end of the war. In the end, only 223 C-82As would be built, a small number relative to other wartime production cargo aircraft. Most were used for cargo and troop transport, although a few were deployed for paratroop operations or towing military gliders. A redesign rectifying the aircraft's main deficiencies, made its debut in 1947. Its subsequent improved design would result in the 1949 rollout of the Fairchild C-119 Flying Boxcar. In 1946, the United States Postal Service explored the concept of flying post offices using highly modified C-82s, which would operate similarly to those on trains where mail would be sorted by clerks and put in bags and then transferred to trucks on landing. In 1948, a C-82 was fitted with track-gear landing gear, similar to the tracks on a crawler tractor, that allowed landings on unpaved, primitive runways. After the C-82A became surplus to United States Air Force requirements, small numbers were sold to civilian operators in Brazil, Chile, Mexico and the United States and these were utilized for many years as rugged freight aircraft, capable of carrying bulky items of cargo. The last example was retired in the late 1980s. For details of the 11 variants, click here.
