The white line you see in the sky behind an airplane is water- water vapor. Known as a contrail (for conensation trail), this is visible when the very large amount of water vapor created by burning jet fuel meets the VERY cold air at high altitudes. Just as you can see your breath on a cold day, you can see the "breath" of the airplane engine. Jet aircraft may fly at 30,000 to 40,000 feet of altitude- where the air is -70 degrees F.
The smoke is actually ice that freezes in the air

It's the fuel from the engines.
The white trails left behind jets are known as contrails.
When you see a white trail behind an airplane, that is what is known as a contrail, short for condensation trail, and it is composed of water vapor, not smoke. This condensation happens because the hot exhaust of the plane's engine meets the colder surrounding air and the mixture of cold and hot air is a sort of miniature weather front.
If you ever see a commercial airliner in flight behind it there will be a white tail folowing it. This is the smoke trail.
some kids taught it how to smoke behind the shed.
Honey bees leave behind white stingers.
No that is what we call a snail.
The white trail you see behind an airplane in the sky is called a contrail. It's an artificial cloud made by the exhaust of jet aircraft or from the wingtips.
No. It is not nearly massive enough. When the sun dies it will leave behind a remnant called a white dwarf.
