Actually all jet planes leave a trail when in high altitude because the air is cold at that height and the water vapour generated by the jet engines freezes instantly into a dust of ice. Propeller planes are less likely to leave a trail due to two reasons - they fly at a relatively lower altitude where the air is warmer, and the turbulent air from their propellers dilutes the exhaust gasses.

so as that phenomenon is noted as a contrail ( a condensed version of "Condensation path") and your grandpa isn't too some distance off. fairly while an airplane is going in the process the sky the nice and comfortable exhaust from its engines could reason water to condense right into a path in the back of the airplane. If the air is chilly adequate, and the airplane is severe adequate then those trails grow to be ice, and are available into view to us, way down under.

Aircraft create contrails which are basically a cloud that forms behind the aircraft. This cloud is formed by the introduction of moisture into the atmosphere from the engine. The contrails may not form even though the engine continuously produces moisture because the atmosphere has not reached its saturation point yet and the contrail cloud can not form.

If the trail is WHITE it is a vapor trail-just water condensing really! If the trail is dark it could be a number of different things-the original f-4 Phantom could be seen for miles beacause the jet engine left twin black trails through the sky-and I have seen a very poorly tuned P-40 leave some pretty dark trails, but he had bad rings on the engine and was burning oil pretty badly

This is known as the "Con trail" for condensation trail. Whether or not it leaves a con trail would depend on the conditions at the altitude the plane is at. If it's flying at a lower altitude generally the air is warmer and the exhaust may not condense to form the trail.
Alos prop planes do not tend to leave con trails, only jets do.

Ones leaving a trail of smoke were shot down

its based on many things, some have engines designed to leave smoke for ads while others do it just because theyre at high altitudes and the engine air coming out is hot and hits the cold water crystals forming that

its the moisture in the air . if you see a long streak behind an airplane at 30 000 feet it means we probably get some rain soon.

They are called contrails and it depends on the temperature of the air where the plane is flying.

*putting on my tin foil pointed hat* Its chemicals the government is putting in the atmosphere. Chemicals to make all the young people old.......yea that's it.
