Biomimicry

"Boeing Co. and NASA have found an inexpensive way to cut airline fuel bills by borrowing a trick from the world’s greatest long-distance aviators: migratory birds. By lining up cruising aircraft in a V-shaped formation favored by Canada geese, carriers would be able to produce a leap in efficiency without investing in structural makeovers or futuristic technology. The idea is to link the flying convoys safely using navigation and collision-avoidance tools that already are widely installed in cockpits."

"The habits and anatomy of birds are being used by boffins at Airbus to develop quieter and more fuel efficient planes. The aviation giant, which makes and designs wings in Broughton, Flintshire, and Filton, Gloucestershire, employs Professor Norman Wood to unlock the mysteries of the natural world to help gain a commercial advantage. 
It is using so-called ‘biomimicry’ in the design of intelligent wings that react automatically to the environment, just as an eagle’s or a peregrine falcon’s do."
