No. If you live in the US, most of the vapor trails you see on any given day are the products of civilian jetliners, not military aircraft.
Vapor Trails was created in -2001-11.
Contrails are clouds that appear behind aircrafts. Contrails are long, thin, man-made clouds that are essentially vapor trails. These vapor trails are created by a change in water vapor or changes in air pressure.

They are called con-trail or contrails, short for condensation trial, they occur when the warm moist from the jet engines enters in contact with the cold air.Also, contrails can be generated on the wingtips, when the air flows over the wing, it travels further and therefore it speed up, causing the pressure drop, wich will cause any water vapor suspended in the air to condensate and form into a cloud.
Their are people that believe that the contrails left by aircraft are some government conspiracy but this is not the case. They are simply water vapor trails. They are triggered by the water vapor in the exhaust of aircraft engines or changes in air pressure over the wings surface.
no they are caused when hot exhaust gases hit the cold air,known as a vapor trail
A cloud chamber can be used to detect alpha or beta particles. It is also filled with water or ethanol vapor. A bubble chamber holds super heated liquids. What do they have in common? They both leave trails.
Water vapor; they are basically artificial clouds formed by the wings.=======================They are called con trails.

It condenses out as droplets or ice crystals.

leave it in the sun or boil it
