Does anybody else think that they spent a surprisingly small amount of time at the new search area indicated by the analysis of the acoustic recordings? And, if I am interpreting the data correctly (which I may well not be), they didn't even cover the search area very thoroughly. It would seem to me that, considering that this is the closest thing they've had to a solid lead for the location of the recorders, they would be concentrating in that area and working outwards from it.
Either way, my fingers are crosses for them finding it - it would be dreadful to leave this event in such a state of mystery.
