I don't think this is the first time he told this story. In fact, he wrote up an incident report the same day which he states he will refer to during the interview.
-Page McClaine 17- "Boy, did he have a pair of landing lights."
I don't understand what your point is regarding this. This is what he thought he was looking and it was the reason later on why he kept looking at the plane. He also noticed that it was off color and the "brightest thing in the sky".
-Page McClaine 18- He decides the two lights are really one light, Yet he was watching TWA constantly for two to five minutes.
Wrong. This is not what he did. He did not decide two lights were one but actually the opposite. He saw one light but because of the brightness and possibly the angle of viewing he considered it may have been two
As far as the CIA zoom theory, you are correct, I don't really buy it. Hey, I don't believe a word Bill or Hillary say but to believe this is a big conspiracy cover up because the CIA theorized incorrectly is a non sequitur based upon the evidence and information that I have seen. If I read up more upon the disaster I may agree with you. I'm just very skeptical when it comes to conspiracy theories, cover ups and such.
As I said earlier, I can be swayed in my opinion because my mind is not made up on this. It's just that the missile theory needs more real evidence in my mind before I can seriously consider it.
I believe he also mentions in there that it couldn't have been a fire or else there would be plenty of radio traffic. You admit you doubt the zoom-climb, but this scenario described by McClaine doesn't fit with the spontaneous explosion, either.
