New ideas given by NASA for the aircraft of 2025.....

Now a days NASA (The National Aeronautics and Space Administration) is well know to all. It is an Executive Branch agency of the United States government, responsible for the nation's civilian space program and aeronautics and aerospace research. Since February 2006, it has started as a mission to "pioneer the future in space exploration, scientific discovery and aeronautics research. Recently NASA has discovered three concept designs for quiet, energy efficient aircraft which it says could be ready for flight as soon as 2025. Lockheed Martin, Northrop Grumman and Boeing these three companies came up with their designs & won a contract from the US space agency to research, develop and test their concepts in 2011, (the 'Daily Mail' reported). It’s really a great innovation from NASA. Their main motto behind it to make “super planes” which
are faster, larger, quieter - and burn fuel more efficiently and cleanly than their present aircrafts.
