I ran across this link this morning ....
Some time after 2004, probably around 2005 the airport was completely remodeled. Prior to that, you could see remains of the original runways via Satellite images.
Jim..thanks for the link. Way too cool. Also led to a link about HF's railroad....very neat. On the 150th. birthday tour we went on in July we drove right past a few of the remaining catenaries for the electric railroad by the River Rouge plant.
Awesome. This man was something else.
He built the first all metal multi-engine airplanes in the U.S.
He had the first airlines with scheduled flights
Had a hotel at the airport for folks that were traveling by plane to spend the night.
He had a hand in developing instrument landing in fog, etc.
He was afraid to fly.
This wa up a while back:
During the Ford Motor Company Centennial a couple of planes landed at the the test track/airport. At least one was a trimotor. Also Ford opened the test track to a drive around. I was in my depot hack and am shown driving on the test track/airport in the movie they made of the Centennial. That is a another story.
