The stream behind a jet is called a contrail. It is actually water vapor that condenses in the cold.
A thin streak of smoke is called a wisp.

Contrails or condensation trails
Smoke trail is the trail of smoke left behind by an aircraft as it flies in the sky.
That line of smoke is called a vapor trail. You can still see it on low flying planes, but it must be a jet plane.

smoke
That is an airplane equipped with a smoke generator. The pilot maneuvers the plane to form letters and symbols with the smoke trail.
If you ever see a commercial airliner in flight behind it there will be a white tail folowing it. This is the smoke trail.
It is called a contrail. The 'con' in contrail is derived from condensation, because mostly, airplane vapour or 'smoke' trails are made of water. Concorde's contrail was the purest with something like 99% of it being water at cruising altitude. As the air is accelerated over the wing, the water vapour present in the ambient air can't stay suspended so it condenses, forming a long thin 'cloud'.
