i'm not sure if you mean that he was laying at the bottom of the slope for six hours, but that's wrong. it took 6 hours from the accident until he got to the hispital.
they first flew him the Lillehammer Hospital, but they didn't have the equipment to fix his leg/amputate it. then he was taken to Ullevaal Hospital, which is in Oslo, about 2,5 hours from Kvitfjell by car.
the crash was bad, i watched it live... it must suck to wake up from a coma with only one leg.
