Has anyone considered where the film came from and why it ends where it does? Every view I've seen of it so far concludes with the thing still going sitting on top of a huge exhaust plume/contrail.
If you were a news cameraman and saw an unscheduled missile launch, at what point would you shut your camera down? I would quit filming when the thing was completely out of sight.
The fact that he quit when he did (or at least that's all the video the tv station chose to release) says to me that he knew it was a jet approaching him. Why they put it on the air suggesting anything else is anyone's guess.
To me the only thing unexplainable is the apparent exhaust flare. I guess that could have been the reflection of the dying sun on the underbelly of the jet.
Shush. You're ruining it! Though I agree.
