A complete feature written for the BBC's popular science magazine BBC Focus.  The core of the piece is the University of Toronto's Project Ornithopter; instigated and led my profesor James De Laurier.  After 33 years of research this amazing craft made the first confirmed, sustained flight of a piloted ornithopter, on the 8th July 2006.  Many thanks to Dr De Laurier and Project Ornithopter.
