American wingsuiter Jeb Corliss admits there were difficulties in his challenge after successfully flying through a valley in eastern China.
New footage from a camera held by a fellow jumper shows just how little margin for error Gary Connery had for his record breaking jump.
A stuntman has become the first person to jump out of a helicopter wearing a wingsuit and land without deploying a parachute.
American wingsuiter Jeb Corliss successfully flew through a narrow mountain valley in eastern China today.
Corliss, who was wearing a headcam, managed to fly through 298-metre-deep valley, which is only 20 metres wide at its widest point and only 3.5 metres wide at its narrowest point.
The mastermind of last year's Olympic opening ceremony, Danny Boyle, has paid tribute to the event's James Bond stuntman Mark Sutton as a "gentle and thoughtful" man following his reported death in a wingsuit flying accident.
Mr Boyle told the Evening Standard: "The show was built from so many contributions from so many people, none finer and braver than Mark Sutton's.
"On behalf of everyone in the show we were all honoured to have him worked with him and to have known him as a friend and a professional."
He added that Mr Sutton's death would be a "huge loss to his profession" and said "all our thoughts are with his family, friends and colleagues".
The stunt parachutist who played the Queen to Mark Sutton's James Bond during the Olympic opening ceremony warned of the dangers of sky jumps yesterday:
all you jumpers/flyers out there, stay safe, make wise choices and know your limits and your locations live to tell your stories one love
It is unclear if Gary Connery's message was sent before or after Mr Sutton's reported death.
Olympic parachutist Mark Sutton's reportedly fatal accident is understood to have happened on the first day of a three-day wingsuit event near Martigny, in the Valais canton, near the French border.
Mr Sutton had been very experienced in using the special jump suits, which increase the surface area of the body and act like a parachute wing, allowing users to glide through the air at high speeds.
A video on Mr Sutton's YouTube account shows him in several wingsuit flights, including this one near Riva del Garda in northern Italy in August last year, which he introduces with a reference to Team GB:
A daredevil wingsuit flyer has glided through a tiny gap in the Spanish mountains while falling at speeds of 155 mph (250 km/h).
Base jumper Alexander Polli conducted a number of test flights in the Roca Foradada Mountains in Montserrat, Spain before committing to his extraordinary flight by jumping out of a helicopter.
Stuntman Gary Connery describes his 2,400ft fall without a parachute:
– Gary Connery, stuntman
I haven't really digested myself what's happened. Absolutely amazing, I'm overwhelmed with the whole crew. I'm so choked with the turnout, it's been an amazing experience.
