Used to do the Loadsheet for the MD-11F's of World Airways when they operated on behalf of MASKargo...used to scare the bejesus out of me!
Luckily, World operated with their own Loadmasters who would have the final say on the loading...get out of Jail card if you will.
What amazed me was the lack of an IHS on the main deck...except for the doorway if I recall correctly. Not a lot to stop a pallet going for a slide...
