Aus 9/11 Wiki
One eyewitness, State Department employee Ken Ford, said he watched from the 15th floor of the State Department Annex, just across the PotomacRiver from the Pentagon. "We were watching the airport through binoculars," Ford said, referring to Reagan National Airport, a short distance away. "The plane was a two-engine turbo prop that flew up the river from National. Then it turned back toward the Pentagon. We thought it had been waved off and then it hit the building."
Another alleged witness (an employee of the state department) who contradicts the official path. The aircraft was nowhere near the Potomac river according to the official story.
He was in downtown Washington DC and could not physically see the aircraft's path within the basin. Nor could he have seen the alleged impact.
