As we covered in a prior post here, Henry Ford built an airport with the purpose of passenger transport.
While most of the items from this experiment are not around in Modern Times- One remaining artifact is an extremely low mileage 1931 Ford "Airport Bus". Tom Wesenberg posted these photos over on the Ford Barn Forums If you have an old Ford you should join the Fordbarn as there is alot of great info to be had there.
From a technical standpoint, note the unique radiator(and Fordson nomenclature- typically reserved only for tractors) and Lincoln style fenders. There is a 1928-early 1929 Drum style tail light but the bus was built in 1931. The cowl & gas tank is completely inside the bus which means fueling of the bus had to be a unique procedure!
This particular bus resides at the Anoka County Airport in Blaine, MN and is viewable only during air shows or other special events. All photos below are courtesy of Tom Wesenberg.
