“...someone thinks they saw Elvis too. So does that mean...Elvis that shot it down?”
If something that stupid is all you can contribute, why not just sit there quietly and learn?
I'm perfectly willing to learn any new evidence either supporting or rebutting the claim TWA 800 was brought down intentionally. But that wasn't evidence. That was the worst kind of unsubstantiated innuendo.
All that blurb told me is that there was something the investigators discarded as unusable, unworthy of further consideration. Conspiracy nut-jobs immediately latch onto the fact something, anything was discarded and decide that must be the real story. They take that as some kind "evidence" of a conspiracy, of a coverup... It's not evidence, it is worthless noise in the pursuit of real information on the event.
So someone shot a video and saw something funny in it. After the crash what, they turn it over to the investigators. They look at it, conclude that what they see is consistent with a MANPAD, they obviously cannot state it is a video of a MANPAD launch. Apparently, there is nothing else to support/link the event captured on that video with the crash 5 days later. So the video is dropped from the investigation and not mentioned again.
Suppressed? You better believe it was suppressed. Why? Because it is just the kind of thing that if/when it gets out, will cause exactly this kind of hand wringing, finger pointing, this-must-be-it jumping to conclusions. After the investigators are satisfied it is not related, they don't want to have to spend time/energy/resources fighting public opinion and media circus refuting every third wild theory involving the video.
If that discarded video from nearly a week before the crash is the kind of "evidence" there is to support the missile claim, then IMHO there is nothing there to see/learn.
