Dennis Pagen has been writing about sport aviation--hang gliding, paragliding and ultralights--since 1975. He has written twelve books and over 400 articles in trade magazines, all related to flying for fun. There doesn't seem to be an end to this activity, for as sports continue to evolve, new techniques and experiences demand definition.
