“I almost cried”.
Are you sure about that?
All of the alert facilities I was locked up in over time, are also imploded just by the passage of time. Oops not quite, I think the bomber alert facilities at Minot, and Ellsworth are still in existence. Physically anyway, but not as alert facilities.
The only question in my mind is what they did with the crew capsules. I don’t recall those being part of the destruction. Around here the buildings above ground are still there complete with fencing.
The Minuteman Launch Facilities (where the missiles were) were blown up entirely and covered in. The Launch Control Facilities were stripped of everything that could be recycled. The underground capsules had ALL metal removed. Even the plate steel liner of the capsule itself was torn off the concrete.
Once that was accomplished the remaining empty concrete “egg” was filled with sand. There is nothing left but those “eggs” and they someday could be mistaken for very large, deep, septic tanks.
