Missing Screws

Every time I fly, somehow I end up over the wing. So I take on the responsibility of checking to make sure that all the screws are in the wing and that nothing is loose or broken. Although I don't think to check that till we are air born, and I am not sure what I would do if I ever saw a loose screw and we were 20,000 ft in the air....it's still I feel an important job. Almost like being seated in the exit row.
