Unlike skydiving, the event featured BASE jumping, which requires divers to jump off fixed structures including buildings, antennas, spans and cliffs with a parachute or a wingsuit. /VCG Photo

The first jump event took place in October 1999 to celebrate the tower's third anniversary and has since become an annual festival. /VCG Photo
