What changes can I try? Do kites glide? What are some applications of kites that I can explore? Quotes: "You have done a wonderful job.

An excellent resource and learning tool for students and educators. An enjoyable stepping stone into the physics of flight. I highly recommend this book." Christine Traboulssi, Kite builder "It is fantastic! This is a comprehensive and readable discussion covering many unknowns of kite flying... the author brings a wealth of experience and practices to fliers of all ages." Geoff Bland, NASA
