I got the story out from Sean Kramer, who is the only one of them who´s still alive.
They had suffered a shipwreck in the Pacific and ended up on an island without any food. The first week they survived on the tins and cans from the ship that had floated on the island. Then nothing. They had a small fire, because one of them had a lighter which surprisingly still worked. They had the few clothes on their bodies. They had money, keys and other things which had meant something in a different world but here, on this naked island, were absolutely useless.
That ain't right!
