GE Aerospace is partnering with NASA to carry out a series of flight tests designed to improve the industry’s understanding of contrails. To be performed over the week commencing 18 November, the ...

Contrails are clouds made of ice particles, which can be created when airplanes fly through cold, humid air. Persistent contrails are estimated to have a warming climate impact. Flight tests will ...

Some contrails can contribute to global warming. Contrails—pure ice clouds (“cirrus”) that form from aircraft exhaust under specific cold conditions—can trap heat in the atmosphere, sometimes creating ...

A new study allays fears that rerouting flights to avoid forming climate-warming contrails could result in inadvertently making climate warming worse. Researchers from Sorbonne Universite and the ...

Four research figures show how contrails appear in two satellite views (left) and two photographs taken from the MIT Green Building. Aviation’s climate impact is partly due to contrails — condensation ...

If you've ever looked up at the sky and seen an airliner flying overhead, you may have noticed white trails behind it. Contrary to the popular urban myth, these are not chemical agents or chemtrails, ...

Contrails conjure a sense of something overwhelming and ineffable, as terrifying as it is beautiful. By Kate Folk I spend most days working from home, in my apartment in San Francisco’s Richmond ...

Non-experts define contrails as condensation trails that form due to the steam left behind by aircraft and which take shape ...

Looking at the sky on any clear or even partially cloudy day, you might see an outline of an aircraft with what seems like white steam trailing behind it. Most people assume that trail is some form of ...
