The conditions at higher levels were drier , The ones at higher altitude were leaving shorter vapour trails as I noticed myself .
What do you class as low ? Those trails are likely to have been above 26,000ft or more likely 30,000+ ?
This 7.30am on the 9th taken from https://planefinder.net/ using the playback function on that site . the altitude information etc is labeled on each plane you can use the same thing to view your own area at 11am Commercial aircraft are often given a direct routing or short cut between waypoints taking them off the standard flight path .
I can tell which aircraft are international or internal by being able to make out the colours and basic shapes of the planes, the internal routes are easy to make out, and the others you need a scope, the large cross seen in my picture I could see the planes more easily, the trails left on the main North South flight paths are West of us and much much higher and cannot be seen even with a scope.
The plane finder is only s good as those it does show.
Thus of no real help in this case.
