Contrails are just condensation from the hot gases leaving the engine of the plane interacting with the cold air in the upper atmosphere.
The white trails left behind jets are known as contrails.
Lightcycles are like bikes but they leave trails behind.
The heat of the engines, especially jets, leaves a trail of white condensation in the cold atmosphere.
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.
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.
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.
The dogs are hot on his trail. Which trail shall I follow? Happy trails to you! Look at the jet trails! Snails leave trails. The newshound trailed the defendant from the trial.
no
"Scat" or feces is left behind on 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.
