true contrails dont last for minuets to hours after the plain is gone, that shit dissipates almost immediately after the plain, A TRUE CONTRAIL, that is, all you see these days IS chemtrails
during WW2, German military figured out to watch the contrails to get a hint on where the Allied bombers were headed. so how long did those contrails persist? 2 minutes? 5? 20?
edit: as an older person, I remember watching the skies as a kid, and seeing plenty of contrails. my father, an electrical engineer in the aerospace industry had to explain to me how the were formed.
Ice crystals stay around for very long time. Plus, contrails are nothing but a water vapor cloud, exactly like a cloud cloud... and clouds dont just dissipate and go away, clouds last as long as the conditions are right to have water vapor there...

False....contrails do linger for hours.....tell me how a “true contrail” is formed?
Who's downvoting this? Contrails often linger for HOURS. It's called WINTER. The persistence of a contrail is determined by atmospheric conditions.

I'm older, too.
