It's been nearly three months since Malaysia Airlines Flight 370 disappeared and now the most promising lead has been discounted.
A U.S. Navy official tells CNN the underwater pings thought to be from MH370 are not from the plane.
Australian authorities heading the search say they've been looking in the wrong place for weeks.
So will the missing plane ever be found?
In interview with CNN's Erin Burnett, the man leading the investigation, Chief Commissioner for the Australian Transport Safety Bureau, Martin Dolan says he is "absolutely sure" that the plane is not in the ping area.
