I may be wrong, but don't most 3-letter identifiers offer weather reporting
of some type? There are probably exceptions, but if the identifier contains
numbers, they don't offer weather reporting. I have seen identifiers change
from having numbers to all letters when they got AWOS. I suppose if they
lose their weather reporting, they could revert to an identifier with
numbers.

I remember reading online about airport identifiers a while back. Now, if
only I can find it again...

So what's with the musical identifiers? A secret evil plot by the GPS

Here's another interesting case, Drummond (Montana) Airport lost its three
letter identifier, DRU (or KDRU) recently. It is now M26. It will be
interesting to see where KDRU pops up next, I don't know of many cases
where
an airport lost its 3 letter id.
