Contrail

Contrails

I discovered this (picture of an) aircraft contrail over Ilkley Moor in my camera, while processing the Thinking Digital images.

Dusk, 3 contrails in view !!

very poor quality, but nice contrail effect

Most people probably pay little to no heed to the jet contrails in the sky above them on a clear day. I notice them due to my interest in aircraft. When I see a contrail I wonder what airline it might be, what type of aircraft it is and where the flight is going. What stories do the passengers aboard the plane have to tell about why they are flying? These two flights were over the skies of Cleveland on a clear day.

Contrails at sunset. The flightpaths N-S and E-W over the Ports. We don't hear the planes, but we can see them.

"Contrails," said Lily. "Lines on the ceiling of the world."

Interesting airplane trails this morning. Shot with the kit lens.

while capturing the new crescent moon a jet liner flew past and the contrail turned red due to the setting sun.

A condensation trail that is left behind by a passing plane, typically a jet plane. Contrails form when hot humid air from jet exhaust mixes with environmental air of low vapor pressure (pressure due to water vapor alone) and low temperature. The mixing occurs directly behind the plane due to the turbulence generated by the engine. If condensation (conversion from a gas to a liquid) occurs, then a contrail becomes visible. Since air temperatures at these high atmospheric levels are very cold (generally colder than -40°C), only a small amount of liquid is necessary for condensation to occur. Water is a normal byproduct of combustion in engines.

Why does the contrail shadow change sides?

Still no clouds in the sky, sometimes the contrails make shapes and patterns..

Contrails, just in case you didnt know, is short for 'condensation trails', and in this instance they are the vapour trails left by the engines, mainly water, and this happens readily above 8000 metres/26,000 feet. where the temperature is below -40°C.. a bit like that trick that you can do in really cold parts of the world by throwing a cup of boiling water into the air, and it turns to snow, nice.

I've shots with 5 or more planes in view, I wonder how many high altitude planes could be captured usefully in a shot...

Nice large to see more detail.

maybe try on black
