Consider that even the cleverest Islamic suicide bomber usually never manages to take out more than a few victims at a time, at best. (They were bested by Breivik in a pretty big way which they are no doubt jealous of).
Tatu Van Hanen and Richard Lynn in "IQ and the Wealth of Nations" calculate the average IQ of Saudi Arabians to be in about the upper 80s range, while other sources* show that a commercial jetliner requires a pilot to have an IQ almost two full standard deviations above that.
[Kwik tangentialization time: in another total HBD-realism Fail, the NYT published on the Front Page today an article on Egypt's frightening population explosion entitled, "As Egypt Birthrates Rise, Population Policy Vanishes", in which not a single word was uttered about : 1) the super-high rates of kin marriage in that country and in the Islamic world generally ; 2) the inarguably terrible physical and mental drawbacks that results from such cousin-marriage. In a sane society the press would be talking about kin marriage and IQ inhibitors all the time, but...]. /off/tangent/off//
In light of this HBD-aware theory (which summarized bluntly: the 911 hijackers did not possess the mind power to successfully pull off such a Massive Attack), consider the implausibility of the Official Narrative from the military / aviation point of view :
Before reviewing the military air defense response on 9/11, it is important to remember objectively what the 'official story' asks the public to believe. According to their narrative, on the morning of September 11, four enormous, fuel-laden, lumbering jumbo jets were hijacked by 19 Arab men with box-cutters and zero in-air flight experience. These slow, unmaneuverable planes were then flown for 1 hour and 45 minutes through the most restricted airspace in the world without eliciting a single military intercept. The most sophisticated military in the world, able to strike dime-sized targets from hundreds of miles away with laser-guided missiles, precision radar equipment, and state of the art aircraft capable of flying well over 1,300 mph, could not locate, engage, nor intercept four wandering jumbo jets. A military that has a budget larger than the combined military assets of every other country in the world could not scramble, intercept and engage any of the radically wayward planes. Even Flight 77, which was allowed to fly unimpeded and crash into the Pentagon one full hour after two jets had been flown into the Twin Towers in NYC, failed to elicit the response and intercept from any military jets. Nor, indeed, did flight 93. A plane that crashed in a Pennsylvania field 1 hour and 45 minutes after the first plane was confirmed hijacked.Read more from this guy here.
I hate, Hate HATE conspiracy theories. But it is becoming increasingly clear that all the false-flag or whatever weirdness behind 911 is the same sort of subterfuge that resulted in Michelle Obama becoming First Lady.
