#3 Glenmore---they never went away. Even during WW2 you could still get time signals by radio.

There is an old adage in aviation: if you are flying along fat dumb and happy, there is something that you are not doing. I had my GPS wink out on me once on top of a cloud deck. I knew my position, speed, and direction every 15 min. Just drew the course on my map and 30 min later I was in the clear.

#5 As an old pilot explained, "Every takeoff is followed by a landing. Plan to survive the landing."

#6 At least the electronics is more stable. Adjusting Loran and other radio navaids with analog circuits was a pain in the patootie.
