He’s speaking with a great deal of certainty for a situation with so many confounding unknowns. I wonder whether such proposals give false hope to families looking for answers. Even if he’s correctly narrowed down the area of the crash, we don’t know anything about the way the aircraft broke up (maybe it hit the water at full speed and disintegrated into small fragments that would not show up as aircraft-shaped on any seabed scan). Maybe the only pieces still identifiable as aircraft debris are the ones that floated off and have already been recovered. Maybe wreckage has already drifted elsewhere, or been buried beneath sea floor silt. Or even if they find the FDR, and even if it contains more details of what happened, it might not contain the true explanation of why it happened.
