The Government Services Administration is auctioning off a DC-9 jetliner that once served as the smaller version of Air Force One, with bids starting at $50,000 on May 15. The GSA Facebook page states the plane flew "Presidents Ford, Carter, Reagan, Bush, Clinton & Bush," and "the Vice-President, First Lady, Cabinet secretaries, 4-star generals, admirals, foreign dignitaries and more."
