Australian Defense Minister David says the search area is in extremely challenging environment. “Remember, this part of the world, this Southern Ocean, has shipwrecked many many sailors in our history in Western Australian. It is rough, sea state 7, you know, there are 20, 30 meter waves, it is very very dangerous, even for big Panamax-class ships.”  Satellites and planes have spotted a possible debris from the aircraft but so far there has no confirmed discovering of any pieces.
