Contrails, the lines of clouds from high-flying aircraft that crisscross the skies, are familiar sights, but they may have an unseen effect on the planet – trapping heat in the atmosphere. Working with Boeing, and other partners, NASA researchers are collecting data to see how new, greener aviation fuels can help reduce the problem.
ecoDemonstrator
The ecoDemonstrator Program is a Boeing flight test research program, which has used a series of specially modified aircraft to develop and test aviation technologies designed to improve fuel economy and reduce the noise and ecological footprint of airliners.
