Default Just a Plane Observation

I realized today, as it's an interest I have, no aircraft are leaving contrails, at all, when normally they would be created above 31,000 to 39,000 feet. The atmosphere must be bone dry with no moisture

Down here in East Anglia, I've noticed that the trails are there initially but don't last long.

You may like my pic, "Kisses - Of death?"

To me, it's interesting, still no trails here and that's tracking several aircraft up to 39,000feet.

And just another silly point, I have never seen so many gliders up at one time.

Glider pilots search for what they call--UP--but how do they find it with no clouds to show them where it is.----

They have an instrument in the cockpit that helps, seem to remember that when I went up in a glider whilst in the RAF.

I think now I remember something about that. By checking the force of gravity they can tell, without external visual aids, whether they are going up or down.
