McDonnell Douglas DC-10 (1970-1990): The DC-10 made its first flight on August 20, 1970. Although smaller than the Boeing 747, its wide cabin gave it a passenger capacity up to 380 (depending upon seating configuration). The DC-10 was designed as a multi-range jetliner capable of operations from airports with relatively short runways, such as New York’s La Guardia with a full load bound for Chicago, or from longer runways, like St. Louis Lambert International for a non-stop flight to London. A new generation of turbofan jet engines, which produced more than twice the power but half the noise of the turbojet engines used on the first generation of jetliners, powered the big trijet. The DC-10 was produced in three basic models: the Series 10 for domestic routes, and the Series 30 and 40 for extended range and intercontinental travel. During the plane’s 20-year production run, 386 DC-10s were delivered. In addition, 60 were built as KC-10 cargo/tanker aircraft for the Air Force. Six commercial models of the DC-10 were developed. The Series 10 model was designed for service on routes of up to 4,000 statute miles (6,436 km). The intercontinental range Series 40, powered by Pratt & Whitney JT9D turbofan engines, had a nonstop range up to approximately 5,800 miles (9,322 km). The Series 30, an intercontinental model had a range of approximately 5,900 miles (9,493 km). The DC-10 Convertible Freighter, first delivered in 1973, can be arranged to carry all passengers or all cargo and is available in the basic Series 10, Series 30 or Series 40. The Series 15, launched in 1979, combines the basic smaller airframe of the Series 10 with a version of the more powerful engines used on the longer-range Series 30s. The DC-10 Series 30F, an all-freighter model, was ordered by Federal Express in May 1984. First delivery was made Jan. 24, 1986. This pure freighter version will carry palletized payloads of up to 175,000 pounds (79,380 kg) more than 3,800 miles (6,115 km).
