Last year a good friend of mine was snowmobiling when he turned over and became trapped under his rig. His pack with all his supplies was strapped to the rack but was thrown clear as he flipped over. Hopelessly trapped under his rig with a broken pelvis he looked at his gear only yards away but could not get to it. Fortunately help came a few hours later as he was on a well used trail.
Jeez, maybe a few yards of cord and one of these in your friend's pocket would have helped:
