The underwater drone scanning the ocean for Malaysia Airlines Flight 370 began its ninth mission Monday with "no contacts of interest" in its last eight, the Australia's Joint Agency Coordination Centre said.
The Bluefin-21 has scanned about two-thirds of the intended territory without finding any sign of the missing plane.
These efforts may be a main focus of the search, but they aren't the only part.
Australia's Joint Agency Coordination Centre announced Monday morning that up to 10 military aircraft and 11 ships would participate in the day's search for the Boeing 777 and the 239 passengers and crew on board.
The weather isn't making the task easier.
Tropical Cyclone Jack is circulating northwest of the search area. And while it won't hit directly, this system should increase winds and rains.
