Any yachtie will tell you that there are literally hundreds of containers that have washed overboard from container ships and that are "lurking just below the surface". I find myself wishing that Tony Abbott had held off from announcing this development until a P3 crew had confirmed the objects were indeed from the MAS 777.
He hasn't, so now I find myself hoping that he got a "set in stone" guarantee from the satellite analysis experts that the debris is not just some junk that's got nothing to do with the 777. If this sighting turns out to be a fizzer, despite all his carefully guarded qualifications to his announcement, he will be made to suffer and to look a total fool by his always ready to criticise political opponents - lead (I hasten to add) by the National Broadcaster.
