The rules and scoring in ski flying are mostly the same as they are in ski jumping, and events under the discipline are usually contested as part of the FIS Ski Jumping World Cup season, but the hills (of which there are only five remaining, all in Europe) are constructed to different specifications in order to enable jumps of up to 66% longer in distance. There is also a stronger emphasis on aerodynamics and harnessing the wind, as well as an increased element of danger due to athletes flying much higher and faster than in ski jumping.
