Mount Fuji (富士山, Fuji-san^?, IPA: [ɸɯꜜdʑisaɴ] ( listen)) is the highest mountain in Japan located on Honshu Island at 3,776.24 m (12,389 ft). An active stratovolcano that last erupted in 1707–08, Mount Fuji lies about 100 kilometres (62 mi) south-west of Tokyo, and can be seen from there on a clear day. Mount Fuji's exceptionally symmetrical cone, which is snow-capped several months a year, is a well-known symbol of Japan and it is frequently depicted in art and photographs, as well as visited by sightseers and climbers. It is one of Japan's "Three Holy Mountains" (三霊山, Sanreizan^?) along with Mount Tate and Mount Haku.

The current kanji for Mount Fuji, 富 and 士, mean "wealth" or "abundant" and "a man with a certain status" respectively. However, these characters areateji, meaning that the characters were selected because their pronunciations match the syllables of the name but do not carry a meaning related to the mountain.

The origin of the name Fuji is unclear. A text of the 10th century Tale of the Bamboo Cutter says that the name came from "immortal" (不死, fushi, fuji^?) and also from the image of abundant (富, fu^?) soldiers (士, shi, ji^?) ascending the slopes of the mountain. An early folk etymology claims that Fuji came from 不二 (not + two), meaning without equal or nonpareil. Another claims that it came from 不尽 (not + to exhaust), meaning neverending.

Yves Rossy (born 27 August 1959 in Neuchâtel) is a Swiss pilot, inventor and aviation enthusiast. He is the first person to achieve sustained human flight using a jet-powered fixed wing strapped to his back. This jet pack has led to his being nicknamed Airman, Jetman, Rocketman and, later, Fusionman, according to his project steps.

Rossy developed and built a system comprising a back pack with semi-rigid aeroplane-type carbon-fiber wings with a span of about 2.4 metres (7.9 ft), powered by four attached Jet-Cat P200 jet engines modified from large-model, kerosene fueled, aircraft engines. His first flight occurred in November 2006 in Bex, lasting nearly six minutes and nine seconds. Yves later successfully flew across the English Channel on 26 September 2008 in 9 minutes 7 seconds, reaching a speed of 299 km/h (186 mph) during the crossing.

Later in 2008, he made a flight over the Alps, reaching a top descent speed of 304 km/h (189 mph) and an average speed of 124 mph.

In November 2009, Rossy attempted a crossing of the Strait of Gibraltar, hoping to be the first person to fly between two continents using a jetpack. He leapt from a small plane about 1,950 m (6,500 ft) above Tangier in Morocco in the direction of Atlanterra in Spain. The flight was expected to take about a quarter of an hour but, due to strong winds and cloud banks, Rossy ditched into the sea, to be picked up ten minutes later by his support helicopter three miles from the Spanish coast. He was flown to a hospital in Jerez, and later released unhurt. The Spanish Coast Guard later retrieved the jetpack (which had a parachute and a float).
