Can just see it.....pre-departure inspection, just prior to push back (or why not on the threshold).....release landing gear doors to inspect bays.....oh dear forgot the 747 doors hit the ground when the aircraft is fueled....oh well back to the ramp for new doors....
If the silly bu....rs want to stow away thats their risk...what ever you do they will try....at least we didn't get sadled with another freeloading imigrant for the tax payers to support....
