“It’s important to remember that water vapor is invisible, and that when the ice crystals form at high altitudes it is a sublimation process. That is, the water vapor sublimes directly to ice and then directly back to water vapor. It never goes through the intermediate liquid water stage.....”

Well, whatever, condensed water becomes visible, only when the temperature, and relative humidity are appropriate, and these conditions are found in the hi-Arctic on a winter's day, and above 20000 feet, where the temperature is below freezing...generally the freezing level, depends on the temperature lapse rate, which for a standard day is -2 degrees centigrade per 1000 ft, hence, if the ground temperature was 20 C, then at 20000 ft, it would be -20C (-2 x 20000/1000)+20 = -20C

Thanks, but I don’t need any more info on contrails, I know all there is to know about them from years of research while combatting the Insane Cloud Posse of chemtrailers.

There’s nothing in the video for me that distinguishes the trail from an airliner’s contrail.

There have been numerous examples of similar contrails posted, including several that also appear to begin at ground level but actually don’t.

The spiralling is common with airliner contrails, so that is not definitive.

The reflecting sun off a contrail can appear as flames, as we’ve seen before when people filmed or photographed high altitude contrails and reported them as fireballs or meteors or flaming UFOs.

The camera angle is deceptive, so the apparent angle of the contrail is also not definitive.

There were many airline pilots in the area who should have been surprised to see such a launch nearby, yet we have no radio reports, no photos, no videos, and no complaints. Yet.

With no evidence of a rocket launch whatsoever, the objective position has to be with the most likely answer, which is “airliner contrail”, until new evidence is presented, of course.
