From what I've been able to find, I gather that these aren't in use in the
US anymore, and haven't been for some time. Seems they're still used in
Canada though, and are still mentioned in the FAR's. Something to do with
L/MF navigation, but I don't know what that is.

Heck, I can't even find mention of them on Gene's site, so they MUST be long
forgotten.

Someone please give me a history lesson here. Thanks.



The last ones I was aware of were in the outer banks of North Carolina.
Not sure if they still exist.
