I am going through my plane logbook, which includes older entries that are not mine.
There are some entries which seem to indicate trips to airports (3-character identifiers), but which are not coming up in my search (AirNav, and a few others, eg the FAA lookup).
I presume that these are now-defunct airports, or perhaps the identifier code changed since then (not even sure if that happens).
My internet search skills have proven unequal to the task of finding what airports these old codes might have been for.
Is there something out there that might have this sort of historical/obsolete airport identifier information ?
