A human-powered helicopter in College Park holds the world title for longest flight of that kind.
An international organization on Thursday certified an 11.4-second flight on a vehicle with four rotating blades that was designed, built and operated by a team from the University of Maryland's A. James Clark School of Engineering, according to a statement from the school.
The pedal-powered flight took place on July 13 and was piloted by biology student Judy Wexler. The Fédération Aéronautique Internationale was the certifying agency.
About 50 students from the Clark school worked on the helicopter. The team is now working on a lighter and more efficient vehicle that they hope to have ready by spring.
