G'day Mark,

Hope all is well with you both.

You are so right, we could have been just like Lemmings!  ;D

It's always about money, isn't it.  Just before I was hired in 1968 the airlines decided to can the navigators and replace them with these new-fangled devices that were supposed to be "more" accurate than the old human. We had sextant ports on the 707, we even had them on the 747, that's how weird it was back then.  You might recall the story I posted a while back about the ocean station ships that were stationed in both the Atlantic and Pacific to aid planes with navigation.  But at the time we were separated by 2 degrees (120 miles) and 2,000 feet so it was a lot more forgiven if an error was made.

I really love the accuracy of today's navigation systems.  As a side note, the fun fact that with GPS we discovered that the prime meridian is actually 100 meters off to the east of the original Greenwich Prime because of slight bumps in the shape of the earth!  :o

Stay well all of you out there, this too shall pass!  ;)
