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.
well realy no, because its not realy a cloud, it is the smoke coming out of the jet, not a cloud actually a jet stream is a wind current in the upper atmosphere that commercial aircraft use to travle faster. The clooud-like trail behind jets are called contrails and would be considered clouds because it is when the heat causes moisture to gather into small clouds... like how warm breath can fog a mirror.
Planes avoid collisions in the sky by following designated flight paths, receiving guidance from air traffic control, and using onboard collision avoidance systems that detect nearby aircraft and recommend evasive actions. Pilots also communicate with each other using radio frequencies to ensure awareness of other aircraft in their vicinity.
A meteor.
Generally these are made by aeroplanes. The local pressure differences caused by the plane's wings may cause air moisture to condense into fog (or cloud) as they pass through it. These streaks are known as vapour trails.
Water is absorbed by tree roots, then released through transpiration into the atmosphere. Water also evaporates from lakes and streams, forming clouds in the sky. These clouds eventually release precipitation in the form of rain or snow, which replenishes lakes and rivers.
The engines create smoke .
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.
the government is honeslty trying to posion us.. its called a chem trail.
They probably could, but all the sky writing I've seen has been done by light prop driven aircraft. I suspect that with intricate work like that, slower is better...not to mention cheaper.
Give your jet steroids.
Blue Star Jets, US Jetways, Jetset Charter, Jet Select Aviation, Private Fly, Private Sky, The Early Air Way, and Elle Jet all offer private plane rentals.

they are planes that go above in the sky during war and drop bomb.....
planes birds stars and what not
plane fly in sky
No only on planes.
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.
