Hi Matt
It was world news at the time, Even islands that didn't have radio or what ever were checked by sea or air, Also it is obvious that the NZ party never did a thorough job of surveying island, Or they would have discovered skeleton whether the remains are from Norwich city crew or Possibly Amelia.
If they did discover bones of the castaway would they have immediately thought Amelia or a crewman of the Norwich City ?
I honestly don't think these new images will shed any light on the hypothesis that we aren't aware of, Just my opinion
They didn't have much to take ashore, Anything i believe the colonists may have found would probably just be classed as being from Norwich City Crew,
As there is no mention of the colonists believing the remains to be of Amelia Earhart, Just Gerald's
Thanks Richie
