Why you posted it in the FS9 section ?
In any case, it's nothing that has anything to do with our scenery, it's a known P3D V5 bug that sometimes objects appear in the air. The only thing you must be sure of, is to install the P3D V5 Hotfix 1, but there's nothing else to do, other than eventually wait for another fix from LM. We surely haven't placed that object in the air...
