"Mentor" looked like a cross between a dragonfly and a Chinese lantern as it soared toward the ceiling of a Toronto research center, its wings flapping furiously. Below, a bespectacled young man gingerly worked the joystick on a remote control. Mentor started hovering in place, and suddenly the sound of flapping was drowned by thunderous applause.
Mentor's maiden flight last spring marked a milestone in the age-old quest to build ornithopters -- aircraft propelled by flapping wings. Developed by the University of Toronto's Institute for Aerospace Studies and SRI International, a nonprofit research and development corporation in Menlo Park, Calif., Mentor is the world's first hovering ornithopter.
cool!
