Anyone who has followed my posts here will be well aware that I have been a critic of the ATSB's determination of "the 7th Arc", and their refusal to "validate it", from way back.
In short, long ago I concluded that it was "a mathematical construct of dubious integrity".
As a consequence, if "the arc" is wrong, it is of no surprise at all that the search on that arc failed to find the aircraft.
The following discussion on Victor's blog might be of interest to some.
The reader is left to ponder the matter, and perhaps draw their own conclusions.
