Contrails are the white trails that planes leave in the sky. They are a type of cloud and are comprised of very fine ice crystals, like a cirrus cloud. If the air at high altitude is humid, then the contrail will continue to accrete ice and can spread...

Contrails are long thin clouds of ice crystals that form behind planes that fly through freezing cold air. Usually, you see them behind jets at around 30,000 feet. If the air they fly though has enough moisture in it already, then these contrail clouds can last for...

Q) How long do contrails last? A) According to all the books on clouds in the last 70 years, contrails last anywhere from less than a second, up to several hours. If depends on the atmospheric conditions at the altitude the plane is flying. It’s unrelated to the...

The Wright Brother’s first achieved powered flight in 1903. They only got a few feet off the ground, so of course did not leave a contrail. However it was barely more than a decade before planes inched into colder air, and the first reports began. The earliest known...

Some people think that persistent spreading contrails are somehow unusual, and are actually something dangerous being deliberately sprayed on the US people by the government, or perhaps for weather control purposes. They call these persistent contrails “chemtrails”. Some of them are very insistent that this is a practically...

Contrails are clouds made from water vapor that condenses then freezes behind a plane engine. Since the engines are on constantly, it seems a bit odd when you see contrails with gaps in them, or even contrails that stop and start. If the engine is pumping out a...

People who think persistent contrails indicate some kind of conspiracy (which they call “chemtrails”), sometimes point to the “dark lines” that sometimes accompany contrails. Since they can’t immediately think of why these dark lines should be there, they assume it’s part of the conspiracy. Either there is some...

Do contrails sometimes persist and spread out? Yes, see the Encyclopædia Britannica article on vapour trails (contrails): Contrail, streamer of cloud sometimes observed behind an airplane flying in clear, cold, humid air. It forms upon condensation of the water vapour produced by the combustion of fuel in the...
