I wonder if the poster is one of us?
Not a chance. Maybe “one of us” is well aware of this as in first hand information, but such a person would know this forum is monitored for such activity as “one of us” posting this.
Such things were monitored by ASA in the late 60’s/early 70’s. I could give you the project name, but who knows, maybe it’s still classified, in operation with much upgraded technology and methods.
The movie “3 Days of the Condor” somewhat resembles the project, and every time I hear the name of the movie I think of the project.
If my memory serves me correct, the beginning of 3 Days of the Condor is on an upper floor. This unto itself reminds me of the project, for their HQ was on an upper floor.
The things one never forgets.
Hmmm!
