In 1961 President John F Kennedy announced that Lockheed Aircraft Corporation was the winner of a contest to design the first US all-jet production military transport. The aircraft was to become the C-141 and first flew in 1963. The aircraft entered service in 1964 and soon began regular trans-Pacific flights to South-East-Asia. The aircraft became the first US jet transport that paratroopers jumped from, and the first to land in Antarctica.
