Aviation and aerospace engineering students at the University of Leeds, U.K., have come up with the perfect design for a paper aeroplane. The design introduces tiny folded winglets on each side of the plane and at the back, as well as cambered wings, which gives it the killer air-time. The secret to a really good paper plane is to minimise the drag and maximise the lift.
Guardian has provided step-by-step instructions for building the plane, Avenger. (You need a Macromedia Flash capable browser.)
