Flying Saucer Designed for Greener Air Travel

Straatsma heads the recently-formed CleanEra project, which aims to design an "ultra-eco-friendly plane" that releases 50 percent less carbon dioxide per passenger-mile than current airliners. The project's "greenliner"—depicted in design illustrations as a flying saucer—would also reduce other pollutants and noise, in line with recommendations from the European Aerospace Commission, ACARE.

"I want to get rid of the image of a cylindrical body with wings," said Etnel Straatsma of Delft University of Technology in The Netherlands.

The plane of the future, in Straatsma's vision, might be as wild as a flying saucer. She and other engineers are toying with lighter materials and some are pondering ideas as radical as returning to propeller-driven planes as an eco-friendly alternative to passenger jets.
