As a kid I remember real contrails, I got mad because they disapeared too quickly.
These new ones are not contrails, but instead are SMOG trails.
Funny how they seem to turn into cirroform type clouds.
And also funny the altitude and speed are low and very slow,and flight patterns are inconsitant with commercial aviation.
Some years back I watched a plane letting out smog trails, and making donuts and cresents in the sky. In the morning we had beutiful blue sunny skys, and at 3pm it was heavy smog, and this was far from any major city. I just know if my car did that, I would be in big trouble. But then again its not a Jet powered vehicle then it would be exempt from all air pollution laws.
