Doing more with much less, British pilots at this year’s Icarus Cup follow in Paul MacCready’s aerial path, staging a highly successful weeklong demonstration of human-powered flight. Airplanes that fly on about a quarter-kilowatt for as long as the human battery can operate the pedals are not new, and significant records have been achieved over the years. The British have long been involved, beginning with the 590 meters flight by Derek Piggott on November 9, 1961 in SUMPAC (Southampton University’s Man Powered Aircraft – note the sexist terminology of the day).

To help foster interest in human-powered flight, The Royal Aeronautical Society formed the Man Powered Aircraft Group in 1959.
