This bullshit about conspiracy theories detracts from a deserved emphasis on those heroic passengers who brought down the fourth aircraft, in a field in Pennsylvania, at the cost of their own certain death.
Now, there's a story. The conspiracists wouldn't know a real story if it bit them on the bum.
So you haven't heard the story about eyewitnesses in Shanksville, Pennsylvania seeing the plane on fire in the air before it hit the ground, and other smaller planes being seen in close proximity to flight 93 then?
There is a school of thought that United 93 was shot down as its takeoff was delayed by over 40 minutes, and passengers who were calling loved ones would've heard what happened in New York and at the Pentagon and would've tried to make the terrorists on Flight 93 fail in their mission.
One thing that makes me wonder about who was actually behind the attacks is the fact that no terrorist group has, if I recall correctly, actually come forward and claimed responsibility for the attacks. When you think of the Bali bombings, the London bombings and other terrorist attacks around the world, Al-Qaeda, Jameer Islamiah and other terrorist groups have been quick to claim responsibility for whatever happened. Actually, in this case, the opposite has happened. In an article which was published in a Pakistani newspaper on September 28, 2001, Bin Laden vehemently denied being involved in the attacks:
I have already said that I am not involved in the 11 September attacks in the United States. As a Muslim, I try my best to avoid telling a lie. I had no knowledge of these attacks, nor do I consider the killing of innocent women, children and other humans as an appreciable act. Islam strictly forbids causing harm to innocent women, children and other people. Such a practice is forbidden even in the course of a battle.

Instead, we've been led to believe Al-Qaeda were behind 9/11 because Donald Rumsfeld, George W. Bush and other people in the US Government let it slip either on the day or in the following week that they thought Bin Laden and Al Qaeda were behind the attacks. Not because they came forward and claimed responsibility for it.
It wouldn't be the first time the US Government had wrongly accused someone of a terrorist attack either. They did blame the Oklahoma City bombings on Muslim extremists, when it was actually Timothy McVeigh who did it.
