I don't remember the aviation industry ever being as dynamic as it is today. Everywhere you look, people and companies are working on new aircraft designs, be they in the form of helicopters, VTOLs, ...

Airbus has begun the flight test campaign for the Blue Condor project, a pioneering research effort to study the impact of hydrogen on contrail formation using a modified glider powered by a ...

Most of us first spot them as children—the white lines in the blue sky that are the telltale sign of a flight overhead. Contrails are an instant visual reminder of air travel, and a source of much ...

The white trails left by high-flying airplanes may be a pretty sight in a blue sky, but bomber crews dislike them for good reason: an airplane may look from the ground like an almost invisible speck, ...

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 ...

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 ...

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.

Assuming that the radiative forcing impact of aviation-induced contrails is sufficiently strong to justify mitigation measures, it is likely that operational strategies that avoid flying through ...
