The picture from the Detroit River, taken from the infamous Duck Factory is about two miles due east from the Grosse Ile Navy Air Station, the training base for many Navy carrier based pilots, including G.H.W.Bush.
The GINAS is pictured here. The circle, called an aerodrome, was used to simulate an aircraft carrier's deck, with markers, so the fliers were always taking off and landing into the prevailing wind.
It is one cool piece of history here in Michigan, which has lots of cool history and lots of problems today, unfortunately. If you know where you're looking, you can see my house in this picture.
