Saturn Airways

Saturn Airways (ICAO designator: KS, and Callsign: Saturn) was a US supplemental air carrier, at the time the US regulatory term for a charter airline. It operated from 1948 until 1976. Its headquarters were located on the grounds of Oakland International Airport, Oakland, California.

History
The airline was initially an irregular air carrier known as All American Airways based at Oakland Airport and used Curtiss C-46 Commando aircraft. In 1959 it became known as Saturn Airways and began operating Douglas DC-6C planes. Larger Douglas DC-7C aircraft were purchased in 1963 from BOAC and were operated on transatlantic passenger charter flights. In 1965 Saturn acquired AAXICO Airlines. In December 1967 and January 1968, respectively, Saturn took delivery of two Douglas DC-8 Super 61CF jets. This allowed it to operate transcontinental cargo and charter flights, some of which included military flights to South Vietnam. Between 1968 and 1974 it had two DC-8 Series 50 planes in its inventory and added a third Super 61CF in 1972. After absorbing the assets of defunct Universal Airlines in May 1972, it added nine Lockheed L-188 Electra aircraft to its fleet. Saturn also operated nineteen Lockheed Hercules aircraft.

Saturn was finally absorbed by Trans International Airlines in December 1976, making Trans International the largest air cargo operation at the time.

The Triple Crown winning racehorse, Secretariat, was flown to Ontario, Canada on a Saturn Airways charter to run in his last race.
