In this photo dated July 21, 2012, two base jumpers wearing wingsuits prepare to jump from the Brevent needle above Chamonix in the French Alps. For nearly two months, daredevils in skin-tight suits with batwing sleeves and a flap between their legs hurled themselves off the Brevent cliff, soaring through the Alpine skies. Last week, tragedy struck: A Norwegian wingsuit flyer was killed when his parachute failed to open. The next day, the mayor of Chamonix-Mont Blanc banned wingsuits. The decision has triggered a debate about how to weigh the dangers of extreme sport against the passion of the thrill-seekers the Alpine town has famously encouraged. (AP Photo/Cyril Duval)
