Date: September 11th, 2001.
Personnel: Unknown [designate A], Unknown [designate B], Unknown [designate C].
A: It's done. The plane targeted at Congress was crashed by those on-board, but the Pentagon and Trade Center attacks occurred just as scheduled.
B: Congress seems sufficiently angry in any case. I don't think the further steps of the plan will meet with any opposition. We should gain the governmental powers we need, and the stock market should move as expected.
A: Good. Have you prepared the conspiracy theorists to accuse us?
B: Yes. All is in readiness. The first accusations will fly within the hour.
C: Er...
A: What is it?
C: Sorry, I know I'm a bit new to this sort of thing, but why are we sponsoring conspiracy theorists? Aren't they our arch-nemeses, tenaciously hunting down and exposing our lies?
A: No, my young apprentice, just the opposite. As soon as you pull off a conspiracy, the first thing you do is start a conspiracy theory about it. Day one.
C: What? We want to be accused of deliberately ignoring intelligence and assassinating that one agent who tried to forward specific information -
A: No, of course not! What you do in a case like this is start an accusation so ridiculous that nobody else wants to be associated with the accusers. You create a low-prestige conspiracy theory and staff it with as many vocal lunatics as you can. That way no one wants to be seen as affiliating with the conspiracy theorists by making a similar accusation.
C: That works? I know I'm not the brightest fish in the barrel - sometimes, hanging around you guys, I feel almost as dumb as I pretend to be - but even I know that "The world's stupidest man may say the sun is shining, but that doesn't make it dark out."
B: Works like a charm, in my experience. Like that business with the Section Magenta aircraft. All you need is a bunch of lunatics screaming about aliens and no one respectable will dream of reporting a "flying saucer" after that.
C: So what did you plan for the 9/11 cover conspiracy theory, by the way? Are the conspiracy theorists going to say the Jews were behind it? Can't get much lower-prestige than anti-Semitism!
B: You've got the right general idea, but you're not thinking creatively enough. Israel does have a clear motive here - even though they weren't in fact behind it - and if the conspiracy theorists cast a wide enough net, they're bound to turn up a handful of facts that seem to support their theory. The public doesn't understand how to discount that sort of "evidence", though, so they might actually be convinced.
C: So... the Illuminati planned the whole operation?
B: You know, for someone who reads as much science fiction as you do, you sure don't think outside the box.
C: ...okay, seriously, man. I don't see how a theory could get any more ridiculous than that and still acquire followers.
(A and B crack up laughing.)
B: Hah! What would you have done to cover up the Section Magenta aircraft, I wonder? Blamed it on Russia? To this day there are still people on the lookout for hidden aliens who overfly populated areas in gigantic non-nanotechnological aircraft with their lights on.
A: So what did we pick for the 9/11 cover conspiracy, by the way?
B: Hm? Oh, the World Trade Center wasn't brought down by planes crashing into it. It was pre-planted explosives.
C: You're kidding me.
B: Seriously, that's the cover conspiracy.
C: There are videos already on the Internet of the planes flying into the World Trade Center. It was on live television. There are thousands of witnesses on the ground who saw it with their own eyes -
B: Right, but the conspiracy theory is, the planes wouldn't have done it on their own - it took pre-planted explosives too.
C: No one is going to buy that. I don't care who you bought out in the conspiracy-theoretic community. This attack would've had the same political effect whether the buildings came down entirely or just the top floors burned. It's not like we spent a lot of time worrying about at what angle the planes would hit the building. The whole point was to keep our hands clean! That's why the al Qaeda plot was such a godsend compared to the original anthrax plan. All we had to do was let it happen. Once we arranged for the attack to go through, we were done, we had no conceivable motive to risk exposure by planting explosives on top of that -
B: Don't take this the wrong way. But one, you don't understand conspiracy theorists at all. Two, they bought the aliens, didn't they? And three, it's already online and the usual crowd of anti-establishment types are already snapping it up.
C: Are you joking?
B: Honest to Betsy. People are claiming that the buildings fell too quickly and that the video showed ejecta corresponding to controlled demolitions.
C: Wow. I don't suppose we actually planted some explosives, just to make sure that -
A: Oh, hell no, son. That sort of thing is never necessary. They'll turn up what looks to them like evidence. They always do.
C: Aren't they going to, um, suspect they're pawns?
A: Human nature 101. Once they've staked their identity on being part of the defiant elect who know the Hidden Truth, there's no way it'll occur to them that they're our catspaws.
B: One reason our fine fraternity has controlled the world for hundreds of years is that we've managed to make "conspiracy theories" look stupid. You know how often you've ever heard someone suggest that possibility? None. You know why? Because it would be a conspiracy theory.
A: Not to mention that the story would be too recursive to catch on. To conceal the truth, one need only make the reality complicated enough to exceed the stack depth of the average newspaper reader.
B: And I've saved the dessert for last.
C: Really?
B: Yeah. You can go totally overboard with these guys. They never notice and they never suspect they're being used.
C: Hit me.
B: We've arranged for them to be called "truthers".
I hereby dub any believers in this theory 9/11 meta-truthers.
I, Eliezer Yudkowsky, do now publicly announce that I am not planning to commit suicide, at any time ever, but particularly not in the next couple of weeks; and moreover, I don't take this possibility seriously myself at the moment, so you would merely be drawing attention to yourselves by assassinating me. However, I also hereby vow that if the Singularity Institute happens to receive donations from any sources totaling at least $3M in 2010, I will take down this post and never publicly speak of the subject again; and if anyone asks, I'll tell them honestly that it was probably a coincidence.
That's not difficult at all. The remote control of the planes was designed to be used in the event of a hijack. That means once activated there is no possibility for anyone on the plane, not even the pilot to do anything about it. Probably the passengers weren't even aware of what was happening because I suppose the pilots didn't tell them "Ahem, I just want you to know that we are no longer in control of this plane. Keep your calm."
The blackboxes could reveal what happened but, conveniently they didn't survive, at least that's the official story.
Regarding the passengers what is hard to explain is why the alleged terrorists don't appear on the passenger lists and all the passengers on the list really died so there is no possibility of someone having flown under false identity.
Edit: Maybe I should make this clear. There were some companies who have a built in anti-hijack system that allows the plane to be overtaken and controlled from the outside. Those are not special planes. More info at: http://www.911-strike.com/remote.htm
