I agree that the "justification" of Cel Nav as
a "backup for GPS" cannot be defended.
GPS is indeed more precise, more reliable and easier
to use.
On my opinion, we do Cel Nav simply because we like it.
As we like sailing. An airplane is faster, more reliable and
easier to use, if your purpose is to go from a point A to a point B.
The reason we sail is not that
this is the best way of transportation.
And Lunars are not the "best" way to find GMT:-)
You can use radio and wristwatch instead.
Alex.
