Starting in 1959, 21 DC-4s and C-54s found new life as ATL-98 Carvairs. The Carvair was designed to carry 22 passengers and five automobiles. This was accomplished by extending the fuselage, moving the cockpit above the fuselage, adding a side-opening nose, and enlarging the vertical stabilizer to offset the larger forward fuselage. These aircraft served as flying ferries well into the 1970s, and two are still airworthy as of March 2008 - one each in Texas and South Africa.
