Human-powered flight is about as green as it gets, although the pilot/powerplant does emit CO2 and some methane during the exercise. A human pilot can put out only about 0.25 to 0.5 horsepower for reasonable periods, with the record holders like Brian Allen flying The 70-lb Gossamer Albatross in its 26-mile cross-channel flight in 2 hours, 49 minutes,.and Olympic cyclist Kanellos Kanellopoulos of Greece flying 71.5 miles between Crete and Santorini in 3 hours, 54 minutes on April 23, 1988. The flight holds the official FAI world records for total distance, straight-line distance, and duration for human-powered aircraft. The British Human Powered Flying Club holds a gathering of the hopeful every year, this year at Lasham Airfield, between London and Winchester. Depending on how one looks at it, only six competitors showed up this year – or amazingly, six competitors who had designed, built, and test flown their craft, showed up this year. Building even a simple airplane is a relatively complex task: dealing with …

Your editor doesn’t know why we continue to name festivals of flight for Icarus, since he was the young, foolish soul who flew too close to the sun and melted his wings. His older, wiser father heeded his own advice and made the trip safely because he was not so bold. Maybe we use Icarus’ name out of respect for his sacrifice. In the spirit of the two mythical aviators and Leonardo daVinci, Italian designer Enea Bossi and builder Vittorio Bonomi oversaw several bungee-launched flights in 1936 with their spruce, balsa wood and light fabric covered Pedaliante. A 17-meter (55 feet) wingspan, twin propeller airplane, the 220-pound vehicle made as many as 40 flights, but the records are apparently hazy on their duration and distance under human power. World War II intervened …
