Young skydivers in a spin over indoor 'flying'

WARSAW, POLAND - Dressed in a white skintight full bodysuit and helmet, Maja Kuczynska spins furiously before diving into a fast-moving sequence of airborne gymnastic moves with the elegance of a ballet dancer.

Soaring into yet another spin, she then floats, twists and backflips in choreographed maneuvers akin to acrobatics or ice-skating suspended in midair. Her expressive and dizzying two-minute display is enthusiastically applauded by the crowd seated around the outside of the wind tunnel.

At the age of 17, the Polish high school student is one of about 20 top indoor skydiving competitors worldwide, who are pioneering the solo freestyle version of a sport they call "flying".
