I grew up in the late '50s and '60s in this neighborhood and always wondered about this concrete tower. Turns out it was built by AT&T Long Lines Division in 1949 using the concrete form construction method. The walls are 1 foot thick reinforced concrete top to bottom. There are old bunks in the lower levels and comm control panel stations in several floors. There is a dolly system too. It was built to withstand indirect nuclear blasts at the time during the start of the Cold War soon after WWII. (Most likely would not survive by today's weapons). At the time, AT&T transmitted microwave communications to other similar towers throughout the Midwest region. If one tower was destroyed the other towers would take up the slack to continue emergency broadcasting during a nuclear war. The tower is 147 feet tall. Interesting to note, the last 5 years the red strobe beacon has been turned off.
I used the Litchi app in pre-programming the entire flight. I edited the orbit in post to change directions. I am just learning Litchi and PP to keep my mind active. Thank you kindly for watching.
