Could you please give a summary or transcript? For the folks who can't watch videos.
As "Balance" said, it is a rather lengthy phone call.
@8:42 in the video, there is a still frame of an engine pylon of a commercial passenger jet, showing the small tubes (circled in red) that have become a common "gotcha" from 'chem'trail enthusiasts...and of course, these tubes are explained as drains already (here on MB).
@8:45 -- Caller:
"I don't know what they are, I'm only speculating.....All it is, is hot vapor hitting the freezing cold temperatures and forming ice crystals..."
Weatherman:
"What you're seeing is just water, water droplets..." (interrupted here) --
Caller:
"....but, these return back to ambient temperature a few seconds later, and that's how a contrail is formed and always dissipated in the past..."
Right there, we see a cognitive disconnect. The caller is polite, but misinformed as to the nature of contrails, and how/why they can persist in some conditions, and dissipate in other conditions.
