I'm assuming that the crew had a gps at least as good as the $99 gps I have, which would show the terrain and roads in the vicinity of the accident. That 4 yr old boy had a compound fracture, among other severe injuries, and received a blood transfusion as soon as he got to the hospital- by road. Because the helicopter couldn't fly. What part of that is it that you don't understand? It wasn't a trivial mistake.
