[Titus Quinctius Cincinnatus]

Folks at work used to make fun of me, now, not a single one of them denies the sky here in our state is made cloudy consistanly by the trails being left behind by jets, I proved it to them over and over again, you can simply watch it happen. I challenge you do so.

Jet engines producing hot water vapour as part of their exhaust, venting into the cold, upper troposphere, make clouds of condensed/frozen water which resembles clouds?

Why yes, you are quite right, I had noticed that. Quite fascinating, actually.

It's tinfoil to spin wild theories as to just what the purpose of these things are, but there is a difference between the two. Contrails eventually dissipate and are gone. "Chemtrails" don't, and linger. On days that have a lot of them, they'll spread out and merge into a milky, hazy cloudcover. The sun can be seen through this layer of whatever it is, with a sort of sundog effect around it, like a refracted halo.

Again, I have no idea what the deal is with this, but there is a difference. If I were to speculate, my guess would be a misguided attempt at minimizing "global warming."
