This brings back a great memory. Around 1983 I was flying in a Qantas 747 from Sydney to Honolulu, at night, and while walking around got into conversation with a steward. Much to my surprise, he offered me to take a look below. I got into an elevator (sort of a dumb waiter) and went down, into a quite large galley storage area. There I was, SLF all alone in the cargo hold area of a 747 over the Pacific!
