Ski flying is an extreme version of ski jumping. The events take place in big hills with a K-spot of at least 185 metres (610 ft). There are five ski flying hills in the world today. Vikersundbakken in Vikersund, Norway; Oberstdorf, Germany; Kulm, Austria; Letalnica, Planica, Slovenia; and Harrachov, Czech Republic. The sixth hill, Copper Peak in the western Upper Peninsula of Michigan, is currently disused, although there are plans to rebuild it to FIS standards. The biggest hill is in Planica, where all the longest ski jumps have taken place. It's possible to fly more than 200 metres (660 ft) in all the ski flying hills, and the current World Record is 239 metres (780 ft), set by Norwegian Bjørn Einar Romøren at Planica in 2005. This record was surpassed by Janne Ahonen of Finland at the same competition, but his 240-metre (790 ft) jump was not recognised as Ahonen fell when he landed.
