Thats where I learned to fly! At Willow Run Airflight, which was near the Aircraft Mechanic School. My grandma worked at the Bomber plant there in WWII. I kept my Aeronca Champ at Larson field, a grass strip near Willow Run Apt in the 70's. Good times. A nice area to fly in too.... wish I could go.
Nearby Grosse Isle aiport, on the isle in the Detroit River was a training base using Stearman's during the war also. Done many touch and goes there... last time I was there I saw 7 or 8 guys with gyro-copters buzzing around in formation. (Another cool airport.)
