Wingsuit expert Gary Connery has told The Sun that his fellow Olympic stuntman Mark Sutton was "smart, articulate and funny", adding:
In any sport where you share a common bond you can make friends in a heartbeat that last a lifetime. My relationship with Mark was like that.
As well as teaming up for London 2012's opening ceremony, the pair also worked together on Mr Connery's successful maiden jump without a parachute, which made headlines around the world in May 2012.
