The Cheyenne mountain bunker is a half-acre cavern carved into a mountain

That seems a little on the small side to me. Is the cavern into the complex a half acre wide and the complex itself still yet larger?

Probably talking about main control room being 1/2 acre.

I thought the same thing....100’ x 200’ doesn’t seem all that large of a space to me either. Hard to put a “whole town” in that space.

I worked inside it in 1970-71. It is much larger. Writer is clearly sitting far removed from there.

Half Acre 148 feet x 148 feet

Half Acre 148 feet x 148 feet seems small for what they are doing

I visited that complex in the late 80’s, It was operational then, all the operational units that housed electronics, controls, housing,etc where on shock absorbers. Lots of huge motorized gates.

I was there at the time to look into building machines that could tunnel vertically, the thinking was if the silos got knocked out then they could put missiles way under ground and if attached the machines would tunnel up and they could launch missiles. Never did though

Half an acre would be 21,780 square feet.

1 acre ~ 210 ft x 210 ft
1/2 acre ~ 105 ft x 210 ft

Very small area. No way it’s that small.
