It's the fuel from the engines.
smoke
The white line left behind a plane is called a contrail, short for "condensation trail." It is formed when hot, moist engine exhaust mixes with cold air at high altitudes, causing the water vapor to condense and freeze into ice crystals.
If you ever see a commercial airliner in flight behind it there will be a white tail folowing it. This is the smoke trail.
some kids taught it how to smoke behind the shed.
When you see a white trail behind an airplane, that is what is known as a contrail, short for condensation trail, and it is composed of water vapor, not smoke. This condensation happens because the hot exhaust of the plane's engine meets the colder surrounding air and the mixture of cold and hot air is a sort of miniature weather front.
Yes sometimes. The white trail is called a 'contrail' and is caused when water in the air through which the plane is flying condenses out on particles produced from the plane's engine exhaust. Thus any plane with an engine can produce a contrail if the conditions are right.
it helps to form all the clouds together to make it rain in areas that need it
passenger side kick panel. Behind it. it is a white inertia switch.
white smoke is water, black smoke is oil. remember that!
The jet contrails are exaust from the jet engines, which is mostly carbon dioxide and water vapour.
There are two kinds of 'white-smoke'. If it dissipates quickly into the air, its just steam (water) no big deal if it goes away in a bit. The second is the kind that hangs in the air and leaves a cloud behind the car. That's OIL. That's expensive!!
white smoke is coming from my exhaust why?
