Aus 9/11 Wiki
"And when the impact hit, the cars and everything were just shaking."
A constant theme in these links. Even the mention of the word ´impact´ makes these people witnesses. Coincidentally the rest of his quote is as follows
Battle, an office worker at the Pentagon, was standing outside the building and just about to enter when the aircraft struck. "It was coming down head first," he said.
This places him at one of the South Parking entrances which has no view of the western facade. He describes the plane´s approach as ´coming down head first´ but totally omits the plane´s arrival on Route 27 and the crossing of the lawn. He obviously FELT the explosion, but lost sight of the plane in its final seconds.
