The area where crews are looking for the devices lies within a larger 217,000-square-kilometer (84,000-square-mile) search zone that 14 planes and nine ships crisscrossed Friday in the hopes of spotting debris on the ocean surface. The search zone is about 1,700 kilometers (1,100 miles) northwest of the Australian west coast city of Perth.
Fourteen aircraft and 11 ships were involved in Friday's search activities in the greater search areas, the coordination agency said. Ships sighted a number of objects in the area but none were associated with the missing plane, the agency said.
The search area has shifted each day, as the investigative team continues to analyze what little radar and satellite data is available while factoring in where any debris may have drifted due to ocean currents and weather.
Australia is coordinating the ocean search, and the investigation into the plane's disappearance is ultimately Malaysia's responsibility. Australia, the U.S., Britain and China have all agreed to be "accredited representatives" of the investigation.
Four Australian investigators were in Kuala Lumpur to help with the investigation and ensure information on the aircraft's likely flight path is fed back to search crews, Houston said. The two countries are still working out who will be in charge of analyzing any wreckage and flight recorders that may be found.
