The Dassault Cargo Falcon 20 is a French jet aircraft that, on April 17, 1973, became the first to carry a Federal Express air package. This was a new milestone in the history of air transport in the United States and created a new category of airline, the exclusive air express carrier. Within a decade, no less than thirty-three were flying on the spokes of the Federal Express network. The service was so successful that, by the early 1980s, its front-line aircraft were expanded to the McDonnell Douglas DC-10Cs, whose cargo holds were big enough to carry several Falcons each.The first Dassault Falcon made its maiden flight on May 4, 1963. It is a well-proportioned, all metal low-wing monoplane, with full cantilever wing and tail surfaces, pressurized fuselage, and retractable tricycle dual-wheel landing gear. It is powered by two aft-mounted General Electric CF-700-2D turbofan engines. For cargo use, the Series 20 was modified by several basic changes, the success of which is a tribute to the inherent soundness of the design. The Cargo Falcon 20 also features an oversized cargo door, measuring 55 inches x 74.5 inches, and a strengthened floor to accept loads of concentrated weight.
