Question

On clear morning Day with no clouds in the forecast you always see airplanes marking up the skies randomly?

Answer 1

I have no idea what you are trying to learn but if it's about those markings in the sky, please don't believe the people saying jet engines. And I have no clue what 'Chocohol' is on, but I certainly hope he's not a pilot!     Jon

Answer 2

yes, it think its jet fuel.

Answer 3

Yeah, even I can make those markings with my Piper Arrow (small propeller plane)... if I can get high enough that is.

Answer 4

Im assuming that your refering to contrails that are formed when water vapor that exits from a jet engine when flying in below freezing temps.

Answer 5

this is a vapor trail from the jet exhaust  at 30,000 ft the temps there even in summer are very cold and since the jet produces at least 30,000+ lbs of thrust the heat temps at least 1200 degrees so the very hot exhaust and the very cold air create this steam mist streaks... someday go for a flight and enjoy the view

Answer 6

water vapour.
