Were you referring to contrails? See below.
Otherwise, yes, the jet stream is a wind pattern that exists in the upper atmosphere, but wasn't really observed, understood, or taken advantage of until the jet age. Hence, it was named the "jet stream".

Maybe you are confused with your vocabulary. The jet stream is a wind current found in the upper atmosphere...has nothing to do with jets, other than the similar speeds involved.
The white trails that come off most airplanes, not just jets, are called contrails. Contrails are actually clouds, if you can believe it. The air flowing across the wing heats up a little in relation to the air not skimming off the wing. This temperature difference causes the water vapor in the warmer air to condense, forming a cloud. As the air cools back to the temperature of the surrounding air, the cloud dissipates.

I'm assuming you mean to ask about the white stream of mist you see following a jet high up. This is a contrail, it's basically caused by the heat of the engine exhaust meeting the cold air . pretty much like a cars white smoke on a cold morning right after its started .

Jets do NOT create the jetstream! The jetstream is a very fast air current in the upper atmosphere. It was always there, even before airplanes! jeezzzzzzzz

A contrail is made by condensation
