Jets leave white trails in their wakes for the same reason that you can sometimes see your breath. As a result, the air is thinner and less dense than it would be at lower altitudes.
The contrail is a thin, wispy cloud of air that is created when a jet engine passes over the ground. It can last for a few seconds or for several minutes, depending on the speed and altitude of the jet.

Why do some planes leave contrails and others don t?
A difference in flight level of 1,000 feet is enough for one aircraft to cause a contrail and the other not. More efficient engines with cooler exhaust gases can form at lower altitudes than less efficient ones. In the case of an aircraft flying at a lower altitude, it is more likely that the aircraft will be in contact with the ground.
Are contrails harmful?
Absolutely not. are they dangerous to humans?. The misunderstanding of the so-called ‘chemtrails’ which presumably represent trails consisting of harmful chemicals is the reason why this question is often asked. They do not contain any toxic substances, and are not harmful to human health. In fact, contrails have been shown to be beneficial to the health of humans and other animals.
The main effect of spraying is to reduce the amount of sunlight reaching the Earth’s surface, which in turn leads to an increase in cloud cover. As a result of this, clouds are often referred to as ‘clouds of death’ or ‘death clouds’. This is because they are so dense that they can block out the sun’s rays and cause severe weather events such as severe thunderstorms, tornadoes, hurricanes, floods and droughts.
These effects are discussed in more detail in the following sections.
Why are fighter jets flying over my house?
Most of the time, they’re used for training. If you don’t want your home to be used as a base for military operations, then you need to take steps to protect your property. The best way to do this is to build a fence around your yard.
This will make it more difficult for helicopters and planes to land and take off. It also makes it harder for your neighbors to see what is going on in your backyard.
Whats the difference between a plane and a jet?
Any plane that has a jet engine is described by a jet. A non-jet engine used in an aircraft is usually called a turboprop. Skyhawk is a propeller-driven aircraft. The term “jet” can also be used to describe any aircraft that is powered by an air-breathing engine (such as an internal combustion engine or a turbine engine).
Do military jets leave contrails?
When flying through a rain cloud, look for the vapor trails that form over and around the wing. Fighter wingtip contrails can be seen below. Often, military aircraft can be seen taking off with a black smoke appearing over their wingtips. In the case of the F-22 Raptor, the aircraft is equipped with an infrared camera that can see through rain clouds.
The camera is mounted on the underside of a wing, and is used to track the plane as it moves through the cloud. This allows the pilot to adjust the angle of attack, which in turn affects the speed at which the jet is able to take off and land.
Why do planes make trails?
Planes create their mesmerizing contrails as they soar high in the thin, cold air. Water vapor quickly condenses around soot from the plane’s exhaust and freezes to form clouds, which can be seen from miles away. “It’s a beautiful thing to see, but it’s not something you can see with the naked eye. It’s something that you have to look at with binoculars or a telescope,” .
How long do contrails last?
Satellites have seen clusters of contrails lasting as long as 14 hours, and most remain visible for four to six hours. Climate scientists are interested in the long-lived, spreading contrails because they reflect sunlight and reflect the sun’s heat back into space. “The contrail is a reflection of the heat coming off the Earth,” said Dr. Michael Mann, a climate scientist at Penn State University and a co-author on the new study.
