Search as I might, I never found an online map of Detroit for the 1920s era before 1936. I was able to get some maps which show the lower east side riverfront as it got filled and built upon.
I had no idea the airport was on the riverfront originally. Could explain why one Nike missile radar IFC there was called Det. City Airport.
