There are two straight roads intersecting at this point, overlaying other features, with legends in Cyrillic, only appearing at zoom level 15. They do not appear in "nearby features" and appear to be an extraneous artefact.

I just travelled this week on the adjoining Yellow Train route and it looks like this airport doesn't exist. Although the train skirts this area at a lower elevation so I couldn't see absolutely definitively, there are no transport links, the area is not flat, it's covered in rocky outcrops, there is no evidence of a runway on certain satellite photo services. I think this tag should be removed. I also note that it only appears at certain zoom levels on the osm web service. Please could someone who knows what they are doing fix this?
