We all depend on GPS in one form or another, be it on our cell phones to locate us on the map or our in-car navigation systems to get us to our destination.

I would guess people would freak out if GPS went down. Look what happened when Facebook went down! Well, the US Navy is seriously considering that scenario and is now training their officers once again in celestial navigation. Check out the story.
