Evergreen International Aviation
Evergreen International Aviation, Inc. was a global aviation services company based in McMinnville, Oregon, United States. Founded in 1960, Evergreen was primarily known for commercial helicopter operations in agricultural and forestry applications. The airline division, Evergreen International Airlines, operated all-cargo Boeing 747 freighters. Evergreen ceased all aviation-related operations in 2013 due to financial challenges.
==History==
Delford M. Smith (1930-2014) founded the company as Evergreen Helicopters in 1960. Smith was a leading innovator in the commercial use of helicopters, and his company was the first to use helicopters for spraying fertilizer and herbicides, spreading seeds and fighting forest fires. Del Smith and maintenance supervisor Norman McGrew developed a helicopter spray system called the "PaceSpreader" which permitted accurate, fast delivery of granular agents over large areas.〔 The PaceSpreader allowed the helicopter to operate at relatively high speeds while still delivering the product evenly and with measured precision. In 1972 the company expanded into the use of heavy lift helicopters, acquiring a number of Sikorsky S-61, known in Southeast Asia as the H-3 "Jolly Green Giant". In March 1973 the massive Sikorsky S-64 Skycrane was added to the fleet, with a lift capacity of 20,000 pounds.
In 1974 Smith became aware that the Johnson Flying Service was looking to sell its assets. The business was a small supplemental carrier that had two 94-passenger Lockheed L-188 Electra four-engine turbo-prop passenger aircraft.〔 More importantly, it held a supplemental air carrier operating certificate which allowed it to operate as an airline. After significant deliberation, the Civil Aeronautics Board approved the transfer in 1975. Evergreen International Airlines was officially formed and incorporated on 16 April 1975 as a subsidiary of Evergreen Helicopters, Inc.〔(【引用サイトリンク】title=Evergreen International Airlines, Inc.: Private Company Information - Businessweek )〕 The business subsequently continued to expand and split into a number of subsidiary divisions. The main subsidiary was Evergreen International Airlines which operated the Boeing 747 as a cargo or tanker aircraft to destinations around the world. The 747-200 "Evergreen Supertanker" can deliver 20,000 gallons of water on a fire, nearly ten times what can be delivered by a conventional forest service tanker such as the Lockheed P-3 Orion.
