Suppose Amelia's plane made it to Mili Atoll. And the japs hauled it away. That leaves poor Parker Aerospace with no real items to find. They hauled it away.
That may be a bit too unqualified a statement, Craig -
Other than - IMO - the unlikelihood of any such thing as an Earhart landing at Mili Atoll, is the search there in want anymore than the rest of us happen to find ourselves in want for?
If one has confidence in a Niku arrival, for instance, then one is faced with what TIGHAR has been doing for many years: pondering those tiny things that can be found to see if provenance to Earhart can be established so as to prove her arrival there. And of course the granddaddy effort - sea search in the area, the now-planned anomaly peek, etc.
Hypothetically, if Earhart made it to Mili Atoll and there was any significant incident with the airplane beyond a normal landing - and a subsequent hauling away by the Japanese, then there should be some chance of surviving doo-dads from it or her possessions about somewhere in the area. First challenge is to find stuff that may be a match; next challenge is to determine a match or not.
In determining a match of airplane stuff, of course it must go beyond 'consistent with a Lockheed Electra' and all the way to 'convincingly of Earhart's craft' - a very tall order for any of us.
But as a practical matter, I fear the sum of your statement is probably true: there is not likely any Earhart related stuff lying about at Mili Atoll. If they search thoroughly and demonstrate that, then the world will know of one more place not to look, won't it? Something to that I suppose.
