Air Force One.
If Contrails are just created and unavoidable
as you all describe, we have had many Presidents flying in the most powerful advanced planes,
that should kick out more water vapor then the average plane.
So why can't you show me a contrail or two left by Presidents?
.....from what I've witnessed they are wayward flying craft without a destination... only to return and splooge more stripes in the sky. I can only hope I'm wrong....
It's for flight planning. Big deal....
....TOP SECRET. That's the key word.

I noticed here in LA yesterday, plenty of contrails. Then this morning, the typical overcast stratus clouds.
Weather is constantly changing. and that's the way it is. The presence of contrails yesterday indicated an increase in moisture present, and today that bore fruit. It may rain this weekend (today is Friday).
Of course, weather is able to be forecast, with the many modern tools available....but, there is still a lot of imprecision in that ability, because there are many factors which contribute to weather, and we just don't have perfection (yet) to be able to account for every variable. That may be possible in some distant future, who knows? Certainly, it is still a dream, now....getting closer, but no cigar as yet.......
What baffles me is the lack of moisture in the air yesterday. It was bright, clear and dry. If moisture is in the air, it is visible.

There have been legitimate news broadcasts of chaffe from so called military jets and it blanketed Big Bear and the surrounding areas.
