On previous page of this thread 'eaglemmoomin' rooominated thusly: "...Though on an aircraft carrier/LHA/LHD would'nt there be FOD checks etc...."
Yessirreebobsir, the FOD walkdown is a feature of USN flat deck life as far as I can tell from Ozland. It is amazing what can be found when one looks - especially of the tiny variety of bits that end up on a flight deck or aircraft line ashore. Most USN docos about CVN life will show the FOD walkdown.
