Something happened to those planes and it is obvious that the Pentagon was a target. Could the plane that augered into the ground in Pennsylvania have been enroute for this Target? That means that they then used a cruise missal as per a backup plan.
We know two planes impacted the twin towers and that provided cover for a controlled demolition. All this leaves a forth plane missing and presumed lost somewhere. What then happened there? Did it auger into the ocean or was it landed and grabbed with the passengers snuffed.
An aircraft would not have collapsed those upper floors necessarily and such floor would provide a collapse structure largely intact in the form of broken slabs. Here we see blast debris and there is no possible explosion with a jet liner of this scale and size. So a targeted modern blast looks best here.
Something took place on 9/11 and it shapes up as a false flag operation to rigger a major war in the Middle East...
