TufFlights airplanes remind me of a penguin hopping in and out of the ocean onto a snow bank. The airplanes are the closest thing to an "organic" feel I have ever seen. I think big gliders certainly are graceful in the air as are a lot of other airplanes but they are still very much an airplane. The TufFlight designs just hop around with a sense of complete animal freedom. Landing on its nose in the snow, bouncing and still keep on flying was a very trick. Well worth visiting the web site.
