Re: [time-nuts] Celestial Navigation instruction being reinstated in the US Navy

Nothing beats an E6-B on your wrist. Lots of people have them. Very few of them know. Great way to have fun at a dinner party. "Pardon me madam: That's an elegant slide rule you have!" On Mon, Oct 26, 2015 at 9:23 PM, Graham / KE9H wrote: > Both the sextant and the slide

It's also interesting that they are not teaching/using printed tables. They enter the readings into a computer to calculate the location... assuming the computer has not been EMP'd or hacked. It's much harder to EMP/hack a book. I was taught the subtle wonders of celestial navigation in
