Just for the heck of it, I wonder what would happen,
if some terrorists managed to turn off the GPS system, or
maybe even better, have it give the wrong positions.

I have noticed that a lot of people seem to say they keep
a sextant and tables, etc, for backup. The problem that I
see with that is it takes a lot of practice to get good at using a
sextant and working out sights by hand. Someone who has
only tried out their sextant on a calm day or on the beach,
may find it hard to get a decent shot on a pitching boat
or ship, and then work out a sight where one slip of a
plus or minus, or wrong column, would make it all for naught.

BTW,

Has anyone seen those German films of the U-Boats during World War II
in the North Atlantic pitching and rolling? I start getting seasick
just watching it. I saw one where a German Officer was taking a noon
sight on a sub like that. They may have been the enemy, but they
sure had guts. (It took guts to stand up to them too)
