Sergeant Maurice L. Bease:
The interview with him is also no longer available at the original link, so if someone can find a cached version, would be great...

Here is the quote from the interview/testimony:
Sergeant Maurice L. Bease, 24, had worked around Marine aviation long enough to know what a fly-by was, and it sounded like one as he stood outside his office near the Pentagon on Sept. 11. Turning around expecting to see a fighter jet fly over, he saw only a split-second glimpse of a white commercial airliner streaking low toward the building, and him! He did not even have time to duck before it plowed into the side of the Pentagon around the corner and about 200 yards from where he stood.
Problems:
1. Does not actually say, directly, that he saw the plane hit. The interviewer has stated it, inferring it from the man's testimony.
