It has lurched almost sadistically from one sighting/false report to another.
What happened a few weeks ago when it was decided categorically that it had crashed off the west coast of Australia and that there were 122 pieces of debris found via satellite?

I know there's a lot of ambiguity in the link but it was directly after that report that statements were made that the plane had definitely met its end there or there abouts.
It's perplexing in the extreme and after this amount of time in those seas the debris field must have spread beyond imagination.
