The heat of the engines, especially jets, leaves a trail of white condensation in the cold atmosphere.
The white trails left behind jets are known as contrails.
Almost all aircraft flying in the high, cold sky leave contrails. These are trails of hot air from engines running in very cold air. In World War 2 the bombers going up high in early mornings left very visible trails.
Contrails are just condensation from the hot gases leaving the engine of the plane interacting with the cold air in the upper atmosphere.
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.
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.
no
the government is honeslty trying to posion us.. its called a chem trail.
Condensation in the low temperature atmosphere of vapours found in the engine exhausts. Its name is a Contrail - condensation trails.
Contrails (short for "condensation trails") or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals.
No that's not true. They never do.
By ships and planes.
What you see is not smoke- they are contrails- short for condensation trails. The air is extremely cold at that altitude, the exhaust is hot, and contains a great deal of water vapor. When it comes in contact with the cold air, it condenses, and becomes visible, like fog or clouds. Ever see the "steam" roll out of the bathroom after a hot shower? Same idea.
