Best Answer

The white trail is called a contrail which is short for condensation trail. The fumes that are emitted from the engines of planes contain a large amount of water vapours. When the plane is at a high altitude, the temperature can be low enough to freeze the water vapour into tiny crystals which we see as a white trail. The trail disappears when the water evaporates.

Yes sometimes. The white trail is called a 'contrail' and is caused when water in the air through which the plane is flying condenses out on particles produced from the plane's engine exhaust. Thus any plane with an engine can produce a contrail if the conditions are right.

Why do airplanes give out white smoke while in flight?

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.
