Interesting mental exercise for Lost devotees:

What supplies-resources could reasonably be assumed to be on a 747 in route from Sydney Australia to Los Angeles?

Significant cargo in addition to passenger luggage?

I'm reminded of Sawyer's struggle with finding suitable eyeglasses....

That would be an issue for me. I don't carry two months of disposable contacts with me on flights. If my glasses were destroyed I wouldn't see the wild boar coming....

The Lost survivors do make shelter use of the fuselage pieces.

As I recall, initially about 40 survived the crash scene where Jack and company landed.
