The problem is that because of trying to make sense of a few visual clues, he's formed the thought that he's looking at a smoketrail that was produced over the timespan of a minute or so. He's not realizing that it was formed over the timespan of an hour or more.
When I look at the video, I see that when the camera zooms in, the contrail grows in length by a lot. Having watched missiles take off, his mind most likely processes that as thinking that it's rapidly growing longer as a result of it being a smoke trail that is gaining length by a missile moving rapidly forward. It's not. It grows in length because the camera is zooming in. When watching the video, if you make the effort to use your mind to filter back out the effect of the zooming in by the camera, you can see that it practacally isn't moving at all, in relation to your point of view. If it was a missile, it wouldn't be practically standing still in relation to the clouds closest to it in the shot, which is what I see on the video.
The Amish Navy is up to its old tricks again.
There’s a lot of fools outing themselves that insist a zoomed in picture of a plane giving off a contrail is some sort of rocket.
