The Unfolding of the Attack: The Jetliners, Buildings, Military, Etc.
Merely examining the timeline of the attack reveals profound red flags in the official story. The timelines provided here look at the attack from a number of different perspectives, and includes both known events (such as the times that the buildings were hit by jetliners and the times that they collapsed) and events unknown except through official pronouncements (such as the times that officials became aware of the attack).
The response timeline according to NORAD is based on its September 18, 2001 press release which contradicted earlier statements by officials that there had been no scrambles of interceptors to chase the commandeered jetliners. The response timeline according to the 9/11 Commission provides a third version of the events, contradicting both of the earlier versions.
