Dear gscholz, in this changeset you have blindly "fixed" a self-intersection of a completely fictional airport that someone had added. Your modification makes it more difficult for other community members to revert the bad edit.

It is good that you are looking out for OSM quality but please keep both eyes open while doing so. If someone sees a horse and maps it as a "kow", and you then "fix" that mistake by changing it to "cow", you haven't actually improved anything ;)
