You are missing my point. It isn’t “found,” and the field isn’t proven to have been “reduced,” until actual pieces of wreckage are found. Until then, while I agree there is a good chance the search area is greatly reduced, it’s just another conspiracy theory.
Like I said, I’m a stickler for details.
The search teams don’t “find” the material unless they narrow it down to a viable search area. That’s what this does.
