With aerial search efforts now suspended, the effort to locate wreckage from Malaysia Airlines Flight 370 will enter a new phase focusing on the ocean floor. Australian Prime Minister Tony Abbott announced on Monday that it was "highly unlikely" surface debris from the missing plane will ever be found, but vowed his country will continue to help locate the plane.
In the 53 days since it disappeared, as many as 26 countries were involved at one time in the search. Today, seven countries are involved in the recovery of the plane and the 239 people on board.
The new underwater search phase will span over 23,000 square miles, roughly the size of the state of Indiana.
