I found this and wanted to share. Has anyone ever seen this type of crack on the wing like this one? I know the reverse has very deteriorated letters due die deterioration. Is this a rare location for a crack?
Hmm. Not sure that you can see that from a picture. I think it could be either depending on the posters answer about the "mysterious line". So? Is it raised or recessed, that is the question.
It is indeed raised, I can see it clearly from a different angle. Here are more pictures. The area below the crack on the edge of the wing shows slight impairment going further down.
