I travelled commercial airlines too and from saudi arabia.I forget the outgoing airline because i was not real happy to be boarding it but our return trip was on Panama Airlines.On neither flight did we have our weapons.They were turned into the armory seargeant before we left.what was done with them or how they got back I do not know.They may have been somewhere on the plane or may have come back on the boat with the trucks but we did not have them though in 91 no one was in the least concerned with our nail clippers.Besides a true grunt can trim his nails with a survival knife or bayonnet(also not on board with us) so we just had to chew em on the way back.
