If the plane flew on AP until fuel exhaustion and then spiralled into the ocean, there would have been fragmentation of the fuselage and release of all sorts of floating items - pieces of composite lining, seat cushions, oxygen masks, possibly life jackets.
I'm not surprised none were found initially - roaring 40's, and several days before we started searching in the current area.
But it is surprising nothing at all has washed up after 12 months.
This makes me think wasn't a high speed crash with fragmentation.
Interesting site where you can input crash location and see where and when debris is most likely to wash up. It obviously depends exactly which position you nominate, but the densest flow of material is generally towards south and then SE coast of Australia (relatively densely populated).

Famous rubber duckie story, but given these float
on of water and are affected by wind, probably different to MH370.
