I liked donee's post about animals ability to morph their bodies to achieve direction without the need of the weather vanes we see on aircraft.I know NASA and MIT,and others are working on aircraft which will be shape-changers during flight.I will watch with much interest as this technology advances.No doubt,active aerodynamic appliances will make inroads into the road vehicle arena,as energy prices,and competitive forces spawn reactive engineering counter-punches.Hope so!
