I had a recent trip where I got a window seat instead of my usual aisle. If I don't want to get up, I don't mind it for a flight of 2-3 hours. But my seat was adjacent to the wing, and I couldn't help observing in detail little scratches and imperfections and dings in it.

Obviously the plane proceeded without difficulty, but does it ever make you nervous to get too good a view of the wing?
