A basejumper filmed his own death while performing a stunt in the Dolomite mountains in Switzerland.
Italian daredveil Uli Emanuele was killed after he jumped from a mountain top, lost control and crashed into rocks before he could open his parachute.
The 29-year-old made his name after performing a jump last year for GoPro's YouTube channel when he used a wingsuit to fly though a 2m wide cave.
Mr Emanuele, who won the Extreme Base Jump World Championship Spain 2010, stated his goal on Facebook: "I focus my job on finding out places never jumped before and searching for new terrain flight lines."
He had clocked up more than 60 jumps so far this year before his tragic accident.
In a video tribute to Mr Emanuele, the World Wingsuit League said: "We are saddened to announce World Wingsuit League (WWL) has lost another great wingsuit pilot and a beautiful human being.
"Uli Emanuele, thank you for your contributions to our sport and thank you for sharing your exceptional talent with the world. RIP."
