Sandblast effect ...
From down the back the other day, noticed the painted RYANAIR logo on both my favorite airline's winglets had been significantly 'sandblasted' with the letters 30% obliterated. When I got off, I noted that the spinner spirals on the engines looked similarly beaten up.
Is this ash damage? I don't recall noticing such wear and tear previously. If so, are Europe's workhorse airlines now getting a better picture of what's it costing in extra maintenance ?
