Yves Rossy circles Mount Fuji with his four-engine jetpack TOKYO, Nov. 8 (UPI) -- A Swiss pilot who became known as "Jetman" when he created a working jetpack said he circled Japan's Mount Fuji in nine flights. Yves Rossy said he and his four-engine device made a ring around the 12,389-foot-tall mountain in nine flights between Oct. 28 and Nov. 3 to celebrate Fuji's designation as a United Nations Educational, Scientific and Cultural Organization world heritage site, the Christian Science Monitor reported Friday. Rossy, a Swiss International Air Lines pilot and a former Swiss Air Force pilot, took his first flight over the Swiss Alps in 2008. He said he is working on improving the design of his Jetwing to allow him to land without using a parachute. The current design is also unable to take off, leading him to jump out of a helicopter with the device for his Mount Fuji trips. Rossy said the current design allows the Jetwing to go as fast as 125 mph.
