Combining two of my favorite pastimes, aviation and cars, Roscoe Turner's 1929 Packard currently is on display at the head of Concourse B at the Indianapolis Airport.
Wow, people traveling to/from Indy are so lucky right now! I wish my airports would have exhibits this relevant to gearheads!
Cincinnati's airport has a nice display of Crosleys. If I remember correctly, they are located on the baggage level near the exits. They look ready to squeeze into and drive away.
