New Scientist on cleaner flying

The cover story of the current New Scientist (24 February 2007) is on ways to make flying cleaner. It includes discussion of such technology as strut-braced wings, laminar flow control, fast forward and the flying wing. The piece, by Bennett Daviss, takes a sceptical view on whether such technologies will ever be implemented. But at least it shows the possibilities of such technologies if humans decide to work on them.
