I photographed these Lockheed VC-140B Jetstar examples in the President’s gallery at the National Museum of the USAF and at Pima.
Six C-140 airframes (the military version of the Lockheed Model 1329 JetStar) were built with the VIP interior and used to transport President Johnson and other high-ranking officials. Whenever a President was aboard it assumed the radio call sign “Air Force One” though Johnson liked to refer to it as “Air Force One Half”. The NMoUSAF’s plane also served Presidents Nixon, Ford Carter and Reagan.
