Transocean Air Lines

Known for the first few months of its existence as Orvis Nelson Air Transport (or ONAT), Transocean Air Lines was a supplemental air carrier, a type of U.S. airline defined and regulated by the Civil Aeronautics Board (CAB), the now-defunct United States Government agency that, from 1938 to 1978, tightly regulated almost all U.S. commercial air transportation. During the time the airline operated, supplemental airlines were charter/scheduled hybrids, legally able to operate a limited amount of scheduled service, which Transocean did, especially towards the end of its existence. Transocean was based in Oakland, California. The airline was among the most operationally capable of the supplemental airlines, regularly operating many thousands of miles from the United States. At times it accounted for over 20% of the revenue of all supplemental air carriers, and it usually was the largest supplemental by revenue. However, Transocean fell on increasingly hard financial times during the 1950s and ceased operating in 1960.

Transocean founder Orvis Marcus Nelson was an Air Transport Command (ATC) pilot during World War II. Upon the end of the war in August 1945, he was sent to Okinawa, where he and several other aviators attempted to organize a new Japanese domestic airline with assistance from United Air Lines. United president Pat Patterson was not interested in the proposal, but introduced Nelson to General Douglas MacArthur, who also rejected the proposal.

Nelson returned to the United States and flew for several months as a United pilot, but was recruited by United management to organize a new airline operation in March 1946. The new airline would fulfill an ATC contract to provide military airlift service between San Francisco and Honolulu using surplus C-54 aircraft. ONAT's first flight operated on March 18, and thereafter the airline carried many American soldiers and sailors home from the South Pacific theater.

Transocean Air Lines was incorporated in California on 21 May 1946. On 13 October 1955, the name of the corporation changed to The Transocean Corporation of California (TCC) and a separate Transocean Air Lines was incorporated. In 1956 the CAB approved the transfer of the operating authority to the new Transocean Air Lines and TCC became a holding company for the airline and its subsidiaries.

Later in 1946, TAL was contracted by Philippine Airlines to provide a transpacific DC-4 charter service between the United States and the Philippines, which was for a brief time in 1946 the only commercial flight operating between the United States and East Asia. The service was extended to Shanghai, Bangkok, and Karachi later that year.

Transocean provided personnel for Pak-Air, an airline in the newly formed country of Pakistan, from 1947 to 1949.

In 1948 Transocean began to operate twice weekly service between Caracas and Rome after making a deal with the Venezuelan government. By this time, it operated 16 maintenance bases in Europe and the Pacific region.

The Chinese Nationalist Air Force hired Transocean to ferry 157 Curtiss C-46 Commando transport aircraft from California to Shanghai in 1948. Transocean refitted each aircraft with additional fuel tanks to extend its range to 2,600 miles and flew the aircraft to China via Honolulu, Wake Island, Guam, and Okinawa.
