 (grin) They must have another method... they need GPS for
themselves. I remember when they were devloping cruise missiles
(before GPS) they used an onboard computer to navigate, but now Cruise
uses GPS. If they blot it out, scratch the Cruise and remote planes,
and all the clever shit.

 My guess is that they switch GPS to encryption. You get clues from
what the USA bans for foreign consumption. DVDs give you a clue, too.

 You won't, either. Japan started WWII and no one had a clue until
they hit Pearl Harbor and took Singapore. Fiendishly clever, are
these Chinese...
