Greg and Gary

Thanks for the information on "running down a sun line." Greg's "Landfall" article gave me a frame of reference, similar to days of old making landfall where latitude was known and longitude was a best guess based on DR.

I've read through the initial reference from Greg to Gary's work, and believe I understand the concept although I have no working knowledge of HO 208. I'll make the naive assumption other tabular methods may work as well (229 or 249).

Being a visual learner, my next step is to use a universal mercator chart and follow through the example, which should help clarify the process in my mind (if an old dog can learn new tricks). Perhaps after that exercise I can follow up with any quasi-informed questions I may have.

BTW It was interesting viewing a 1940's document that was "declassified".
GCT (Greenwich Civil Time) vs GMT vs UT. I wish they would make up their minds :-)
