Maybe not to a neophyte.
How many engines did UPS jet flight 902 have?
Three
Plane contrails dissipate faster.
Not necessarily. Depends on atmospheric conditions, altitude, winds aloft, humidity, barometric pressure, time of day, engine type, etc.
That would have been my guess that UPS flies 3 engine jets, but I didn’t go look to see what they fly. As for this subject, I haven’t seen conclusive proof what made the contrail. I’ll go with unknown.
