This weekend, 40 teams will compete in the Red Bull Flugtag in Cincinnati, Ohio. Teams of up to five people will attempt to fly their homemade, human-powered flying machines over the Ohio River. The teams will be judged on flight distance, creativity, and showmanship. Designs range from tacos to a one-eyed, one-horned flying purple people eater. This is the only Flugtag event in the U.S. this year and the first time the event will be held in Ohio in over 20 years.
