It’s all about “increasing your chances” and you don’t increase your chances if you divide up your search in two major area - both the “northern route” and the “southern route”.
With this latest analysis from Inmarsat and AAIB (UK Air Accident Investigations Board) and zeroing in on this area — the chances have increased.
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.
