(CNN) – As a new report brings up more questions about how exactly Malaysia Airlines flight MH370 was lost, the mission to find it continues.
The unmanned autonomous vehicle Bluefin-21, which uses underwater sonar, has up until now focused on an area surrounding the location of a detected ping, possibly from the plane's data recorders.
But with no sign of the plane, the underwater search must move on to nearby areas where they hope to find evidence.
Australia's former aviation minister and Ambassador to the U.S Kim Beazley joins CNN's "The Lead with Jake Tapper" to discuss.
