I’ve seen aircraft contrails all my life. My best friend was in the military for years — he expressed no doubt that this was no aircraft — though he thought it was one of our fired covertly. I, on the other hand, believe it very possibly could have been the ChiComs.
One thing is certain after viewing the video several times. This was NO aircraft. An airctaft does not rise in that way, leave a trail in that way, nor have “fire” belching from it back end that way.
Red fire?
