Anyone who is in to adventuring in the wilderness will at some time find themselves in remote locations with no communication to the rest of the world. When in the back of beyond, you still have loved ones to consider at home and a responsibility to them and yourself to seek help if something goes wrong. Depending on where you are, you may not readily have outside help available.
Fortunately, there is a solution to a dilemma or emergency, there is a way to call for help… from above.
