I'm kinda skeptical of the witness on CNN. Some of his statements sounded like he was simply watching TV while being interviewed, but claims to have been parked in a car on the freeway shoulder watching planes coming in. Said the police were asking him to leave when a police car rolled by where he claimed he was (2 cars back of a white van), but there was no sirens or loudspeakers heard in the background while he was talking. So who knows right now.
News conference getting ready to start.
I think the CNN witness 'Corey Marx' was a fake. Originally he claimed he was calling in from the roadside, but just now he was talking about "see those cars moving eastward in your shot"? So unless he lives nearby and got in front of a TV while they were doing another interview, that is hard to explain.
Always be skeptical of eye witnesses, hence the TWA "missle" theory folks.
