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.
Planes that fly at high altitudes, typically commercial jets, leave vapor trails, also known as contrails. These trails are composed of water vapor, created when hot exhaust gases combine with cold, humid air in the atmosphere.
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.
Fast aircraft create vapor trails or "contrails" when the water vapor produced by the engines condenses in the cold, high-altitude air. In a turn, the aircraft's wings generate higher lift and induce a drop in pressure, causing the water vapor to condense into visible trails.
no they are caused when hot exhaust gases hit the cold air,known as a vapor trail
Water vapor; they are basically artificial clouds formed by the wings.=======================They are called con trails.

Water leaves the ocean through evaporation, where water molecules gain enough energy to escape into the atmosphere in the form of water vapor. This water vapor can then condense and form clouds, eventually leading to precipitation in the form of rain or snow.
It condenses out as droplets or ice crystals.
