For Mr. Smiths edification and enlightenment I have a tattoo of an anchor on my forearm and a medal to go with it, both obtained whilst serving my country as a member of the Australian Fleet Air Arm. It is somewhat faded today but I still recall that memorable run ashore in Hongkong back in 1960 when I and a few other shipmates became "Badged".
I am retired now, but that tattoo did not have any bearing on my character or the wonderful forty year career that I enjoyed as an airline pilot much of which was spent as a Check & Training Captain on a multitude of aircraft from DC3s to 747s.
Having been on several pilot selection boards I would be more concerned with an applicant who displayed such tunnel vision, than one who sported a tattoo.
