Although doubts have been raised on whether searchers are looking in the right area for the missing Malaysian Airlines airliner MH370, authorities remain confident the search efforts are still on track.

Australian Transport Safety Bureau (ATSB) Chief Commissioner Martin Dolan said after continued analysis, experts from the Search Strategy Working Group (SSWG) still hold that MH370 had crashed south of an imaginary line known as the 'seventh arc' in the South Indian Ocean.
