Every one of those points has been gone over a hundred times. None hold water. You are right about one thing the contrailscience analysis is about the Leyvas video (what else would it be about?) but none of it is from the Leyvas video. It was all created from flight path data based on an assumption that AWE808, oops, UPS902 created the plume. That's it, an assumption. There is no evidence, just analysis, that the two are the same. And the analysis is very weak.
As opposed to the counter analysis which is simply "That looks like a missile because I say it does." Got it.
