A question to all Americans?

There are so many disputes over what TRULY happened on that horrific day in U.S. history - was it a conspiracy led by sick-minded military personnel to help justify our invasion and subsequent "freeing" of Iraq and to help put a target on Bin Laden's head? The evidence provided by the photos should have required a more in-depth investigation, especially since there is ZERO airplane debris except for the miraculous black box and a light!! Perhaps a plane's engine could have caused the damage captured in the photos, but where's the rest of the plane? why is the impacted wall only seared by the flames and there isn't more damage to the exterior wall? Was there a military response to shoot down the ill-fated Boeing BEFORE it struck the Pentagon? We may never know because of our government's elusiveness to provide THE truth to the American public, and the world for that matter!
