In 1985 the pair of Boeing 707s used for presidential transport were becoming old and outdated so a request was issued for an aeroplane with at least 3 engines and a range of 6000 miles without refueling. The Boeing 747 and the Douglas DC-10 were already the two main contenders. Reagan ordered two 747's for immediate usage. The VC-25's were completed in 1986 and first flew in 1987 with the interior being based on the Southwest and being designed by Nancy Reagan. However, problems with the interior wiring prevented the VC-25s from being delivered until 1990, during the term of George H. W. Bush.
