Cox, Richard (Arlington po)

Aus 9/11 Wiki

Three blocks further along, at the intersection of Columbia Pike with South Wayne Street, 
Police Motorcycle Officer Richard Cox observed the airliner flying so close to the ground 
that the polished underside of its fuselage reflected the images of the buildings it passed 
on its flight; then he heard an explosion.

He is alleged to have seen the aircraft well before the Navy Annex, with no view of the Pentagon basin. He doesn't contradict the NoC flightpath.
