Hello and welcome to my corner of the internet.
I love to see the contrails when the sky is blue and cloudless like that :)
Me too! :)
We appear to be on a flight path too. We always wonder the same as you!
.....and they always seem to be the same distance from us. We look for ones overhead, but don't seem to have those. Like you say, there's a flight path, which for us is over the hills :)
Going or coming? We wave to them when they are all headed back home! ;)
Fascinating where they are going or returning back from. I can see how a novelist would get stories about them all :)
....the mind races with the possibilities! ;)
