This is a great link over on Casts from the Pasts on the History of the Ford Proving Grounds and Ford Airport.
Link here to Casts from the Past
I won't get into the history of the Airport here as the link above does a most excellent job of covering it.
However as you should expect here at Vintage Ford Facts- We dig a little deeper and present the seldom seen side of Ford History. The source of the information presented on Casts from the Past came from Paul Freeman's excellent Abandoned Airfield site which you can read here.
Here is rare 1928 Footage showing the new Model A Fords going thru their paces at the Ford Airport/Test track.
Here's a photo of Edsel and Henry Ford with the "Maiden Dearborn II" Ford Tri-Motor at the Ford Airport in Dearborn around 1930.
