A bright dot, and then one -- you know, the term contrail doesn't really apply, because that's kind of streaking plasma, superheated ionized air.

When conditions are right they leave a "contrail" of vaporized lube in the air.

"CONdensation trail". We've all seen 'em. Did you know how they were made? Condensation, when conditions (primarily altitude)are just right, around particulate matter emitted by the jet engines. They contribute significantly to cloudiness in general in the skies. When virtually all planes were grounded after the 9/11 event, scientists were able to briefly, uniquely, study just how much of a contribution contrails are to atmospheric dynamics.

Soft, distant thunder.
From silvery sky-speck glints,
Silent contrails drift
