Those are called contrails and are caused by condensation.

Yessiree, they are called contrails. Contrails are seen trails of condensed water vapor made by the exhaust of airplane engines. because of the fact the nice and cozy exhaust gases cool interior the encompassing air they might precipitate a cloud of microscopic water droplets. If the air is chilly adequate, this path would be made out of tiny ice crystals. because of the fact the main aspects of jet exhaust are carbon dioxide and water vapor, the nearby advance in water vapor can push the water content textile of the air previous the saturation factor. The vapor then condenses into tiny water droplets or deposits rapidly into ice it is seen to you on the floor. Contrails are frequently formed above 26,000 feet above sea point. The airplane forming them may be militia jets or a advertisement airliner, or a corporation jet, given which you're probable asking bearing directly to the jets you notice above 26,000 feet. altitude. they might come from any form of airports or militia bases international and are going to 3 different airport. Pilots fly them. Contrails are actually not particular, they sort continuously and criss go the sky. they'll quickly deplete. reckoning on atmospheric situations, contrails may be seen for decrease than some seconds or minutes, or would persist for many hours.

They are called contrails, and they are either water droplets or ice crystals, depending on the temperature at that altitude.
They weren't just left behind by jet engines, either. Check out some film footage from the old WW2 bomber raids on Germany -- lots of contrails there, too, because burning a hydrocarbon fuel generates carbon dioxide and water vapor.

They are called contrails.
They occur when close to the dew point causes the moisture to condense due to the reduced air pressure at the wing tips.

Contrails....it is basically just dense steam-like condensation formed when the escaping heat from the plane's engines heats up the condensation in the air around the plane.

When jet fuel is burned it produces H2O and other gases. At that altitude it is cold so the water condenses into a cloud.

Contrails are condensed water vapor, much like you see coming out of your car's tailpipe on a cold day.

Condensed water vapor. It is basically an artificial cloud.
