Have you ever watched an airplane fly across a clear, blue sky? Sometimes it's easy to trace an airplane's path because it leaves behind a white streak across the sky. After a while, though, the plane's track fades and disappears into thin air.
Those white streaks planes leave behind are actually artificial clouds. They're called "contrails," which is a shortened version of the phrase "condensation trail."
Airplane engines produce exhaust, just like car engines do. As hot exhaust gases escape from a plane, the water vapor in the fumes hits the air. At heights of 26,000 feet or more, the air is extremely cold (sometimes more than -40° F!).
The cold air causes the water vapor to condense. This means the water vapor gases turn into tiny water droplets or even freeze into tiny ice crystals before eventually evaporating. This condensed water vapor and mixture of ice crystals make up the cloud-like trails you see in the sky.
If you've ever seen an air show, you may have seen airplanes creating messages in the sky with what look like clouds. Are these contrails? Not exactly…
Skywriters use small airplanes equipped with special smoke machines to fly in special patterns to create written messages visible from the ground. The smoke machines usually consist of pressurized containers full of oil. At a pilot's command, the machines spray oil onto the plane's hot exhaust system, where it burns quickly and creates clouds of dense white smoke.
Pilots have to learn how to fly special patterns and work the smoke machine carefully to be able to create their unique messages in the sky. From advertisements to marriage proposals, the messages can be practical, personal or just plain silly.
Skywriting goes way back. There are reports of successful skywriters before World War I, possibly as early as 1915. Today, skywriters take advantage of satellite navigation to program messages before flight, thereby increasing accuracy.

Why are airplanes leaving trails of a white substance in the skies around the world that last for hours and seem to form clouds?
Because those trails are clouds. The airplane's wing sheds low pressure vortexes from their tips, the low pressure encourages condensation of water vapor to form the small droplets of water that make up clouds. The airplane's jet engines emit lots of water vapor in their exhaust. Often at the very cold temperatures where these airplanes fly (above 30,000 feet) the water droplets in these clouds freeze, becoming ice and making the clouds last much longer.
How can make artificial clouds?
By using chemicals suchas white dense fumes
Why does the sky turns red?
The sky turns red because the sun shines through the clouds and make the clouds seem red when they are just white like normal clouds
Does Airbus make Airplanes or Cars?
Airplanes.
Do airplanes make clouds?
Yes, airplanes can create clouds under specific conditions. These clouds, known as contrails, form when hot, humid exhaust gases from the aircraft mix with cold air at high altitudes. The water vapor in the exhaust condenses and freezes into ice crystals, forming visible trails behind the aircraft.
What is the name of the clouds that airplanes make when they release water into the atmosphere?
Airplanes do not release water into the atmosphere. Those cloudlike trails that you see following aircraft are called "contrails" and they are caused by the agitation of the air by the aircraft passing through it, causing water molecules suspended in the air to collide and join to create droplets.
Why do clouds tern black?
All clouds are white, meaning the water droplets that make up a cloud scatter light in all wavelengths so they combine to produce white light. Clouds appear dark if they are in the shadow of other clouds or, sometimes, if the top of the same cloud produces a shadow on itself. There is also a darker look to some clouds if the background color is bright sunlight, making a great contrast.
Is Cumulus a storm cloud?
No, cumulus clouds usually indicate fair weather. They are the puffy white clouds that form on sunny days. Occasionally, though they can develop into cumulonimbus, the clouds that make thunderstorms.
What do flight engineers do?
make airplanes
Why was Boeing started?
To make airplanes.
Are airplanes made in the US?
Some airplanes are made in the US, but not all. there are several other countries int he World that can make airplanes too.
What is the white smoke that comes out the back of a plane when its flying?
it helps to form all the clouds together to make it rain in areas that need it
