Skysurfing
（重定向自Skysurfer）
Sky surfing is a type of skydiving in which the skydiver wears a board attached to his or her feet and performs surfing-style aerobatics during freefall.
The boards used are generally smaller than actual surfboards, and look more like snowboards or large skateboards. The attachment to the feet is normally made removable, so that if the skydiver loses control or has difficulty opening their parachute, the board can be jettisoned. Surf Flite was the first sky board company, copyrighted by Jerry Loftis (January 1, 1969 – August 12, 1998).
