David will be sure to thank you graciously for not answering his question and being smart-alecks. *rolleyes*
The question was not "do you like AirNav?" but instead "why are there day-old METARs on AirNav?"
This has happened before but I forget the outcome.
I don not have the answer but I would report it to the AirNav webmaster. Though I suspect that he already knows. The METARs and TAFs are completely blank for me today so they might be working on it now. (better blank than incorrect, IMHO)
If anybody finds out what the problem was, please be so kind to post here, I am curious about the cause and resolution.
