You can certainly make the argument that the FBI, CIA, and NSA (and other US intelligence services) dropped the ball on 9&amp;#x2F;11, but NORAD did not.  NORAD&amp;#x27;s primary goal has never been to stop terrorism&amp;#x2F;hijacking from occurring on passenger planes within the United States, but rather to warn of enemy planes and missiles from _entering_ the US. (this did change somewhat after 9&amp;#x2F;11, but that&amp;#x27;s after the fact...)&lt;p&gt;Frankly, I stopped reading the article after this line, because clearly the author doesn&amp;#x27;t know what they&amp;#x27;re talking about.&lt;p&gt;But if you&amp;#x27;re interested in this sort of thing, I&amp;#x27;d recommend starting here:  Strategic Air Command: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Strategic_Air_Command&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Strategic_Air_Command&lt;/a&gt;&lt;p&gt;I just finished reading Command and Control by Eric Schlosser, it&amp;#x27;s a pretty decent primer on early US nuclear deterrence and such things as SAC and NORAD.  (though there are better books specifically about SAC&amp;#x2F;NORAD, this is an overarching general&amp;#x2F;popular history.)</text><parent_chain></parent_chain></comment><story><title>Inside NORAD&apos;s Cheyenne Mountain Combat Center</title><url>http://thememoryhole2.org/blog/inside-norad</url></story>

We went on one of the last public tours of the facility in April of 1996 (IIRC).&lt;p&gt;None of the doors in the buildings had any indication of what went on behind them, just numbers, or maybe number-letter combinations. We followed our guide through a maze of these featureless corridors with the anonymous doors all closed, then were ushered into the command center.&lt;p&gt;It&amp;#x27;s pretty small, maybe holds 20 people around a conference table in close quarters. The folks who monitor everything in the world were right next door. One wall is a glass partition between the two rooms, but they pulled a curtain over that because there was some incident going on right then that we were not authorized to see.&lt;p&gt;Then we got a walking tour of much of the rest of the underground complex. The tunnels are wide and high, and there are big reservoirs of water and diesel fuel along the sides.&lt;p&gt;It was really fascinating. Of course no photos were allowed, but I still have a fairly good mental picture of parts of it 20 years later. The photo of the gigantic blast door took me right back - we walked through that very spot.&lt;p&gt;Edit: Thinking about it more, the most surprising thing was the scale of the place. It&amp;#x27;s a quarter mile from the tunnel entrance around the bend (meant as a way to diffuse the energy from a nuclear blast) to the big steel door. We all rode a bus back to that point. We walked about a half mile or maybe more to near the bottom of the other end of the main tunnel. If you look at the diagram in the story, it doesn&amp;#x27;t do justice to the sense of how much work went into carving out the middle of that mountain.&lt;p&gt;The conference room where command decisions were made might have only held 12, not 20. It was very small and spartan. I remember thinking, Shit, the fate of the world might be decided in a room smaller than our conference room at work.&lt;p&gt;Also, it might have been April 1998, not &amp;#x27;96.</text><parent_chain></parent_chain></comment><story><title>Inside NORAD&apos;s Cheyenne Mountain Combat Center</title><url>http://thememoryhole2.org/blog/inside-norad</url></story>
