When highly experienced caver George Linanne fell during an expedition in the massive Ogof Ffynnon Ddu cave system in Wales , he wondered whether he would ever reach the surface. With a leg broken in two places, and multiple injuries to his jaw, collar-bone, chest and internal organs, he was in excruciating pain. Some 300 cavers from across the UK took part in what became one of the longest cave rescues in UK history. George tells Dr Sian Williams about his accident, his incredible escape and why he is back caving - the sport he loves - as well as becoming a cave rescuer himself.
