Major Plane Makers Join Forces To Develop Biofuels.

AFP (3/23) reports Boeing, Airbus, and Embraer "announced on Thursday a joint plan to develop affordable biofuels for the airplane industry." This work "is intended to come up with a so-called 'drop in' technology that all airplane models could use, regardless of the make." All three, who called for a "unity" in purpose, "said they were committed to reducing the industry's substantial carbon footprint."
