the government is honeslty trying to posion us.. its called a chem trail.
The heat of the engines, especially jets, leaves a trail of white condensation in the cold atmosphere.
The white trail is called a contrail which is short for condensation trail. The fumes that are emitted from the engines of planes contain a large amount of water vapours. When the plane is at a high altitude, the temperature can be low enough to freeze the water vapour into tiny crystals which we see as a white trail. The trail disappears when the water evaporates.
Comets leave a trail of white dust behind them because as they approach the sun, the heat causes the icy nucleus of the comet to sublimate, releasing gas and dust particles into space. This debris reflects sunlight, creating the bright white trail known as a comet's tail.
jet plains have a white trail behind because of the moisture for some time. in higher layer of atmosphere where there is hot air to disturb it. this trail is suspeded for a long time
smoke
Water vapour.
The white trail you see behind an airplane in the sky is called a contrail. It's an artificial cloud made by the exhaust of jet aircraft or from the wingtips.
The white trails left behind jets are known as contrails.
They used small white rocks
Tap water can leave white residue behind because it contains minerals like calcium and magnesium. When the water evaporates, these minerals are left behind, forming the white residue known as limescale.
The streams that jet planes leave in the sky are called contrails. Contrails form when the hot, moist exhaust from the airplane engines mixes with the cold air at high altitudes, causing the water vapor to condense into ice crystals. Contrails can sometimes linger in the sky for a while, creating long white streaks behind the plane.
I think this is write but it says in my textbook that later looking back we realized our trail breaking role. I believe that this means that they broke the trail of just white air pilots since they were black and they flew planes.
