Brad, I was thinking the same thing. That they did not get a lot to shore based on those assumptions, including:
1.The radio messages describe injuries
2. The first surveys of the island describe extreme difficulty in transporting cargo across the slippery reef and note that in the future supplies should be easy to carry
3. At first they were so tired from the flight they just slept in the plane at night.
4. That they simply expected someone to find them for the first few days.
5. The lack of things found. (could be because colonist already scavanged them).
6. The number of radio messages imply they spent a lot of time in the plane, maybe under the wing during the day where they put some boxes or luggage to sit on and keep above a few inches of water
I think the list should inlcude what they usually had on them and could survive 75 years such as lighters, glasses, shoes, belt buckles. Then the items like food and water containers, first aid kit, small luggage bag.
I added the first aid kits because I think they may have found pieces of a metal box at the Seven Site that could be the First Aid Kit, something they were likely already using before leaving the plane
http://tighar.org/smf/index.php/topic,18.0.htmlThe thing I find interesting is reports of wreckage being seen years later, which implies she could have attempted to salvage more, but couldn't
My theory is she was scouting when she ended up at the Seven site. I think her leg may have been hurt and was using a crutch and she needed shoulder straps to carry stuff, including the Sextant box (see my sketches in the Join the Search section about the little clips) and First aid kit had connections for a strap. The benedictine bottle may have had a cord wrapped around it.
