The official story is a consipiracy theory, and the craziest one of them all: that a dialysis patient living in a cave in Afghanistan with a laptop and 19 idiots with boxcutters who don't know how to fly could defeat the world's greatest airforce, and successfully hit the most well-defended building on Earth, the Pentagon.
It does not require hundreds of thousands to pull this off. There were lots of war games going on on 9/11, including ones of having hijacked planes, and planes crashing into towers. All it takes is a number of people in key top positions to direct this operation; most of those involved either were patsies being told a false story to get them to take their part, or were simply following orders and told nothing about the plot, simply follow their orders and don't ask questions.
Anybody involved will keep quiet to avoid the electric chair. Others like FBI's Siebel Edmonds and MI5's David Shayler have been silenced with gag orders and threatened with jail if they talk.
So it does not take thousands of conspirators. A small number such as 19, for example, in high places would be enough.
As far as keeping secrets, the Manhatten Project was kept secret for many years. Many other projects may have been kept secret for longer and we still don't know about them because they are kept secret.
Here are just a few anomalies. There are hundreds more where this came from:
REMARKABLE FACTS ABOUT 9/11 (0 / 0)
1. The Mysterious Collapse of World Trade Center Building 7 It is commonly known that the Twin Towers fell on 9/11, but did you know a third World Trade Center high-rise building also fell that day? WTC Building 7, a 47-story steel-framed skyscraper, never hit by any airplane, located one block from the Twin Towers, collapsed at 5:20 that evening, imploding in the exact manner of a professionally engineered demolition. It fell suddenly, straight down, at near freefall speed, and landed in a compact pile of rubble, barely damaging any of the surrounding buildings – and these are but a few of ten characteristics of Building 7’s collapse that are consistent only with controlled demolition. It takes a team of skilled people many weeks to design and implement large demolitions. GW Bush’s brother was a director of the company in charge of security for Building 7 and the WTC. Astonishingly, there is no mention of WTC Building 7’s remarkable collapse in the 571-page 9/11 Commission Report.
2. Pools of yellow-hot 1500+ degree molten iron at Ground Zero lasting for weeks can only be accounted for by powerful explosives.
3. The sudden, explosive, and total destruction of the Twin Towers at freefall speed vertically into their own footprints can only be adequately explained by controlled demolition using powerful explosives per basic laws of physics according to university physics and engineering professors. The government’s account is impossible since it violates basic laws nature and physics. Free fall speed can be achieved only when there is sudden loss of all resistance below, as occurs only in the case of precisely timed, professionally planned controlled explosive demolition. The government refuses to debate its story about how the towers fell.
4. Whenever contact is lost with any airplane, fighter jets routinely take to the air to investigate. This commonly occurs about 65 times per year in well under 20 minutes. But on 9/11 nearly two hours passed without any interceptions of airplanes.
5. Osama bin Laden has never been indicted for 9/11. 6) The FBI admitted June 2006 that there is “no hard evidence” linking Osama bin Laden to 9/11. 7) There is no mention of any 9/11 crimes on Osama bin Laden’s “wanted poster” on the FBI’s website.

The sole confession video of bin Laden is thought to be a fake.
9. The 9/11 Commission Director’s academic expertise is in the creation and maintenance of, in his words, “public myths.”
10. A Zogby poll found a whopping 42% of Americans believe there has been a 9/11 cover-up, and another 10% are unsure.
11. Security for the WTC, United Airlines, and Dulles Airport was headed by GW Bush’s brother Marvin Bush, and GW Bush’s cousin Went Walker III.
12. Several of the alleged 9/11 “suicide hijackers” are reported alive and well, per the BBC, The London Guardian, and other sources.
13. Alleged hijacker names do not appear on any of the flight manifests.
14. At least five of the alleged hijackers reportedly received training at US military bases, per Newsweek and other sources.
15. Financier of alleged hijacker Atta met with top US officials during week of 9/11.
16. Atta and other allegedly “devout Muslim hijackers” indulged in cocaine, lap dancers, alcohol, and pork.
17. The Bush Administration resisted the formation of the 9/11 Commission for 441 days, whereas similar investigations, such as those for Pearl Harbor, the JFK assassination and the Space Shuttle disasters, all started in about one week.
18. Four courageous 9/11 widows finally forced the 9/11 Commission into existence and presented many questions, most of which were ignored. Under the leadership of Bush administration insider Philip Zelikow, the commission’s report failed to address any of the evidence pointing to official complicity.
19. The Secret Service broke all established protocols on 9/11 by allowing President Bush to remain in a well-publicized classroom “photo-op” long after it was known that the US was under attack and he might have been a target.
20. There were warnings of impending attacks from at least eleven other countries, as well as several FBI agents. Also prior to 9/11, insiders such as John Ashcroft, top military officers, and San Francisco Mayor Willie Brown were warned not to fly.
21. Key counter-terrorism officials who failed to stop 9/11 were promoted after 9/11.
22. Insiders made millions on bets made just prior to 9/11 on falling prices of American and United Airlines stocks yet their names were never revealed and they were never investigated.
23. In Sept. 2000, a group of neocon hawks, many of whom would become key officials in the Bush Administration, wrote that their proposed massive military buildup would proceed slowly “absent some catastrophic and catalyzing event – like a new Pearl Harbor.”
24. A Scripps poll found 36% of Americans think it “somewhat likely” that US government officials had some complicity in 9/11.
25. The WTC steel was never fully examined or tested for evidence of explosives, but instead was quickly melted down: an unprecedented violation of federal crime scene laws & the largest cover-up of evidence in history.
26. More war games than ever in US history coincided on 9/11, including drills involving hijackings and crashing a large plane into a large office tower, yet the role of multiple war games in allowing the 9/11 attacks to succeed was never addressed by the 9/11 Commission.
27. FBI and CIA whistleblowers have been silenced with gag orders and threats of jail.
27. Operation Northwoods signed by Chairman of US Joint Chiefs of Staff proposed killing Americans in staged terror incidents to create a pretext for starting war.
28. Testimony reveals V.P. Cheney monitored the plane approaching the Pentagon, yet he did nothing to evacuate the Pentagon or engage antiaircraft missiles.
29. The government refuses to release mountains of crucial 9/11 evidence.
30. CIA’s Operation Mockingbird spends billions to influence media news organizations.
31. The 9/11 Commission knew that government officials had committed perjury, yet they omitted this fact from their report.
