... seven weeks ... no closer to understanding what happened ... no closer to identifying it's final location. How can this be? It has to be time for a fresh look at all the available data and a re-think of the whole situation starting from scratch.
Nobody knows what happened but the authorities clearly believe it ended up were they are looking and they know more than we do. The defined area has not been properly examined. If nothing is found either the search wasn't good enough or it isn't there. Time then for the next big decision.
