I found this today while looking at the Daily Mail. I wonder if this may be a possible answer as to why MH370 hasn't been located.

He told the Sun that investigators have wrongly worked under the assumption that the plane was out of Shah's control after its final contact with authorities on March 8, 2014.
'I think [the search team] may have gone wrong with the assumption that the aircraft wasn't under control at the end,' he said.
'We were taking this quite seriously during the search, that the aircraft may have continued to be under control in one form or another after it crossed the 7th Arc.
'Once that had happened, the aircraft was probably further south.
'...if the aircraft was still under control at the seventh arc then the size of the Indian Ocean they could of of reached is so unimaginably large that you wouldn't have been able to afford to search it all.
'There was a whole lot wasted effort looking in the wrong areas.'
He says he believes the theory of Simon Hardy, a Boeing 777 expert who posits that Shah was 'suicidal' and deliberately flew the plane towards the Geelvinck Fracture Zone.
BBM: I wasn't aware of the theory that the plane wasn't under control when it went missing. I thought the general assumption was that one of the pilots had control of the plane.
My other question is would the debris that has been found be in the same areas it has been located at if the plane crashed in this area that he thinks it did?
