Question about these trails, whatever they are.
I've always been fascinated by planes, and am constantly sky watching for them.
If you are looking you will notice many planes leaving trails and others at the same altitude not leaving trails.
Why do some planes leave a trail and some don't?
Also, why do some of these trails disappear immediately and some linger for hours and even end up creating what appears to be cloud cover.
