Interesting.
On a recent road trip, my son and I were looking at the contrails. On some days, they stretched across most of the sky. On other days, about halfway. One day, we saw only a short contrail behind one plane and none behind another. We wondered if the short or missing contrails were because of excessive dryness in the upper air.
Of course, we also shared a couple jokes about people who believe in "chemtrails."
“...people who believe in “chemtrails.”
Yeah, there’s a few of them.
