Thompson's 9/11 timeline has long been the indispensable resource for those doing serious research into 9/11. But it has also served as an excellent introduction into problems with the official story. It does this simply by showing discrepancies between this story and hundreds of stories in the mainstream press (to which Thompson restricts himself). My own work on the subject began, for example, by studying the material provided by Thompson, and this material has remained my primary resource.
It is great that this magnificent labor of love--love for the truth--is now available in book form, so that it is far more widely accessible. The Terror Timeline, furthermore, is not simply the material that was previously available on the Internet. Rather, Thompson made many last-minute additions, responding in particular to reports by the 9/11 Commission.
One can never know, of course, what the effect of a book will be. But my guess is that if people begin reading The 9/11 Commission Report in conjunction with Thompson's book, the Report will start getting fewer 5-star and far more 1-star reviews.
