Goldstein, 1965 

IFC Radar Towers at Promontory Point, aka Nike Missile Site C-41 (demolished 1971.) As far as I know, this is the only movie that used one of Chicago’s Nike missile sites as a filming location.

Curious City just did a write up about Chicago’s former missile sites, and The Man on Five compiled more links and information on the subject. My favorite is “Sunday in the Park with Chicago’s Cold War Missile Defense Shield”, via Pruned.
