Aus 9/11 Wiki
Describes a "20 passenger jet" that he saw out of the "corner of his eye".
However he was first reported as saying :
"Out of the corner of my eye, I saw this plane coming down. I was talking on my cell phone to my wife about how close I was to the airport and then I saw the fireball."
He saw the fireball as opposed to the plane "striking" the building. Assumption.
Doesn't describe flightpath. Concerning the angle, he said it "looked like it was landing".
Doesn't contradict NoC and his description of a small plane shows how little detail he caught, out of the corner of his eye.
