It appears as though the barnacles attached to the flaperon may (as hoped for) be able to provide some refinement of the likely ocean-entry site.
If the creatures are identified as a particular sub-species (
Lepas australis), this would suggest the Southern side of things, as this species does not inhabit warmer, more Northerly, waters but is confined to cooler conditions (i.e. Southerly latitudes).

Of course, there will be counter-arguments....
