1) The day before 9/11, on 10th September 2001, Donald Rumsfeld announced that $2.3 trillion dollars cannot be accounted for in defense spending. Reports of that were effectively buried due to the events that unfolded the next day.

2) It is argued that President Bush knew 911 was going to happen because of comments he made 3 months later. According to official reports he was told about the second plane going in to the WTC by a security officer who came into the room where Bush was visiting with a group of school children. However, in the video below, he says he had already seen a plane go into the WTC before he went into the classroom - but the pictures of the first plane crash were not even known about by the media until the next day and only the second plane crash was shown on live TV. This ties in with the conspiracy arguments that the footage of planes going in to the WTC were all faked - the suggestion is that maybe he saw some of the fake footage that was going to be show later, or maybe he was just confused...
3) The planes that flew into the World Trade Center: Look at this picture of the plane that flew into the South Tower of the WTC:
Video of plane going in to the WTC South Tower including the flash...
There is something strange about this footage. As the picture and video, above, shows there is a yellow ball of flame when the cockpit of the plane hits the World Trade Center. But when the wings hit (with the engines and the fuel) they just go into the building with no yellow flame at all. Why is there a yellow ball of flame when the cockpit hits when there isn't any fuel there to burn? Some argue this is evidence that the plane was in fact some kind of missile. Others argue that the footage is completely faked and the video CGI experts just got it wrong. What on earth is the large bump under the plane? [September Clues, In Plane Sight]
4) The Pentagon plane...
It is said that the FBI meticulously collected all of the evidence of what flew into the Pentagon in security camera footage soon after 9/11 (the only released evidence is here but that just shows the explosion and not what went into the Pentagon.)
So the only evidence we have is from the footage taken from the news crews and individuals on the scene at the time. This includes images following the crash, and through the collapse of a part of the Pentagon... All of the following images were taken from the documentary In Plane Sight.
Pictures of the Pentagon before it collapsed, but after an alleged Boeing 757 crashed into it:
Measurement of Boeing 757 that supposedly hit the Pentagon:
But the crater left (after the collapse) seems too small...
Looking closer at details of this crater some strange things can be seen - like a chair with a book on on the side of the crater (second floor center) and the computer screen on a filing cabinet on the top floor center...
5) Building 7 collapses even though it was not hit by a plane, in the style of a controlled demolition. The biggest tenant of the building was Salomon Smith Barney (hence why the BBC refers to it as the Salmon Building) however tenants of the building also included the United States Secret Service, the New York City Office of Emergency Management, The Department of Defense (DOD) and Central Intelligence Agency (CIA).
Here's a video that compares the collapse of Building 7 with a controlled demolition.
BBC Announce that Building 7 has collapsed before it had.
The BBC have said that the report was taken from Reuters, who had in turn taken it from a small agency. The report was quickly withdrawn. But the suggestion remains that the news agencies were acting just like a mouth piece for the government cover up, as if they were just relaying the script of the day's events but had gone a step too quickly in reporting the fall of Building 7. The WTC 7 building is in the background when the BBC reporter is talking about it - it sounds as if she is just reacting to the studio presenter who told her that the WTC 7 building had collapsed, which is indeed what she now claims.
6) The Twin Tower's both collapsed at close to free fall speed. Either this means it was aided somehow with explosives in the building, or the conspiracy being covered up is how a building like this can ever be built in the first place.
What seems to be a definite conspiracy was that the authorities told the population that it was safe to go back into the area when they knew asbestos has been pulverized in the collapse of the Twin Towers.
7) The George W Bush administration conspired to either organize the attacks or, at the very least, allowed them to take place. The evidence for this, conspiracy supporters argue, comes in the form of a policy document - Rebuilding America's Defenses: Strategy, Forces and Resources for a New Century (pdf, size: 852KB) - which was written a year before 9/11. The report was authored by leading members of the Bush administration under the name of The Project for the New American Century (Dick Cheney, Donald Rumsfeld, Paul Wolfowitz, Jeb Bush were contributors to this report). The report says that it would only be possible to fully secure America's defenses in the world if there was a 'catastrophic' or 'catalyzing event', 'such as a Pearl Harbor'.
Michael Moore's movie Fahrenheit 911 argues that the Bush presidency used 911 to radically increase powers at home and to increase a climate of fear, so that it could wage wars which will increase America's influence in other areas - American business has much to gain from the reconstruction and oil in Iraq. In a meeting after 11th September, Bush was keen to find a connection with Iraq so that it could be attacked.
8) The World Trade Center buildings were supposedly brought down by intense heat of the engine fuel burning. However if that is true, then how come this woman is standing by the impact hole in the World Trade Center?
9) Stories of an extremely rare power down event at the Twin Towers on the weekend before 9/11 in which security was non existent and engineers were able to come and go at will without security cameras, or security locks etc to log/prevent their actions. The power down was apparently to replace some cables. These allegations came from Scott Forbes in 2004, and Gary Corbett (reported September 2010) who worked for The Fiduciary Trust. The power down began after close of business on Friday and returned Sunday afternoon. [Source: world911truth.org]
