I think it's educational to note that US Navy aircraft carriers, probably (or at least arguably) the single most powerful and capable weapons system on the face of the Earth, still run the flight deck operations using a totally manual system. The reasoning is that the air boss will still be able to coordinate the deck dance even if power cuts out, or systems get scrambled.
Kind of suggests the smarts behind learning pencil and paper navigation BEFORE learning how to use your GPS.
Of course, I don't think this guy really understands GPS systems either, or he would have thought about underwater hazards to navigation.
How do stupid people get so much money?
