Whoops, typo on my part. It should be M52, not M51…and it’s Franklin-Wilkins, not Williams.
I just have no idea how these airfields that have been closed for so long even got in the game. M52 was closed 17 years ago, and 0M1 well before that. 0M1 doesn’t even appear on sectionals any more. M52 at least is still listed as a closed airfield in sectionals and the yellow Xs are weathered to a point where an AI scanning the map might not notice them, so that might explain why it’s still in the game. The data set they are using must be certifiably ancient. Oddly enough, the airport that replaced both 0M1 and M52, Beech River Regional Airport (PVE), is bugged and has no lights in the game.
Still no idea where they got the KWAV from…no airport has ever existed there, certainly not one important enough to be assigned an ICAO code. The only airport near the small town of Waverly is 0M5 (Humphreys County Airport).
