Future aircraft could cut fuel use by 70%

CNET News (Terdiman) - By 2035, new designs and technologies could help commercial aircraft burn 70% less fuel than today, according to researchers at the Massachusetts Institute of Technology. Armed with a $2.1 million NASA grant, MIT is studying a "radical change" to the aircraft design used for the past 50 years. Instead of an "easily recognizable 'tube and wing' structure," MIT researchers are promoting a "double bubble" design or an integrated wing concept.  Hat Tip: AIA dailyLead
