I photographed these McDonnell Douglas VC-9C Nightingale “Air Force Two” examples at Castle AFB and the Evergreen Museum in McMinnville, OR. Sometimes referred to as “Air Force Two”, this version of the McDonnell Douglas DC-9 airliner modified to serve Vice Presidents (sometimes Presidents) and other leaders and First Ladies from 1975 to 2011.
Interestingly enough, the two examples I have seen are numbered sequentially: 73-1681 and 73-1682.
