austin carey , 23 , and jay rawe , 25 , plummeted onto a riverbank when their parachutes tangled at the perrine bridge , idaho , and were left badly injured .
but a year later , after intensive recovery , both men have returned to the sport they love - and mr carey has even retraced his steps to successfully jump from the bridge .
the pair had been attempting a risky ` totem pole waterfall ' manoeuvre when jay lost his balance and pulled out his friend 's parachute .
