Ken Blackburn, who holds multiple Guinness records in time aloft for paper airplanes, has posted this website dedicated to making paper airplanes. He provides links to websites with information on paper airplanes and images with accompanying text on the how-to's of paper airplane folding. Planes submitted by visitors to the website are also posted and he encourages others to send in their models. An essay on paper airplane aerodynamics offers an in-depth discussion of “why paper airplanes look different than real planes,” explains the Reynolds number, and addresses other important aspects of flying such as Dihedral, weight, launching, and gliding. A section for teachers includes a guide for curriculum-based activities and explanations of relevant topics as well as some links to other websites. Visitors can also read about his experience competing for the Guinness record, find out about clubs or upcoming contests, or read a history of the paper airplane. This site is also reviewed in the November 19, 2004_NSDL MET Report_.
