Contrary to what some people seem to believe, contrails are not a way for the evil governments of the world use to poison us. They can, however, be harmful to the environment, with some studies ...

IN THE SKIES OVER MONTANA ― It was a six hour flight that officially didn't go anywhere, but could help usher in a new chapter of aviation sustainability. A high altitude series of science experiments ...

If you look up in the sky during a sunny day, you might see long, skinny looking clouds coming from behind planes. Those are contrails, short for ‘condensation trails.’ Airplane engines produce them ...

Contrails form when soot and water vapor emissions from jets mix with humid, cold air. Photo Credit: TinaSova20/Shutterstock A cross-section of airlines, academic institutions and technology partners ...

The challenge of addressing aviation’s non-carbon dioxide emissions is receiving greater attention, with the climatic impact associated with tell-tale signs in the sky coming under increased study.

Analysis of in-flight emissions from an Airbus A350-900 using 100% sustainable aviation fuel indicates a reduction of 35% in soot particle numbers, and a halving of contrail ice-crystal formation per ...

Research says aircraft burning a 50/50 sustainable aviation fuel (SAF) blend produce 50 to 70 percent fewer ice crystal contrails at cruising altitude. Using a 50/50 sustainable fuel blend can reduce ...

The warming effect of aeroplane contrails on Earth’s climate could increase threefold by 2050, according to new research done by Lisa Bock and Ulrike Burkhardt at the German Aerospace Centre in ...
