But an underwater sub that spent weeks scouring the seabed in the area near where the signals were detected found nothing, and the Australian Transport Safety Bureau, which is helping head up the search, this week ruled the area out as the plane's final resting place.
• The search is now on hold for two months while new, specialized equipment can be brought in to scan a 700 kilometer by 80 kilometer (430 mile by 50 mile) arc of ocean that was largely identified by an analysis of hourly transmissions, or "handshakes," between the plane and a satellite. The seventh and final handshake involved a logon request consistent with a plane powering up its satellite communication equipment after a power interruption -- leading investigators to believe the plane had nearly exhausted its fuel supply.
• With the origin of the underwater pings now in doubt and the search stalled, what do the officials heading up the hunt for Flight 370 have to say? Here, Martin Dolan, chief commissioner of the Australian Transport Safety Bureau, answers some of the most pressing questions:
