Australia: MH370 Not Fall in Place Search For It
Signals are likely to come from other manmade sources, such as ships that are nearby.
Authorities in Australia have concluded that the aircraft Malaysia Airlines Flight MH370 does not fall in the southern Indian Ocean region where electronic signals detected last month.
Estimation was made on Thursday (29/5) following the last mission of small unmanned submarine which scans the seabed from the southwest coast of Australia.
 In a statement, the Joint Agency Coordination Center said submarine Bluefin-21 did not find any signs of wreckage in the search in an area of ​​850 square kilometers on the seabed.
 The agency said the Australian Transport Safety Bureau has made a professional judgment that the region "can be removed from the possibility of last place" aircraft that Malaysia Airlines.
 The Boeing 777 carrying 239 people when it disappeared from radar without danger call on March 8, about half an hour after leaving Kuala Lumpur to Beijing.
The news came a day after U.S. Navy officials doubt the electronic signals that direct searchers to use a robotic submarine was coming from the missing plane.
Deputy director of the U.S. Navy's marine engineering, Michael Dean, told CNN that authorities almost universally convinced the sound of "ping" it did not come from the plane's black box or cockpit voice recorder, as previously thought.
 Dean said that these signals may come from other manmade sources, such as the ship was nearby or from electronic devices used looking for these signals.
 A navy spokesman, Chris Johnson, Dean dismissed the statement as "speculative and premature." In an email, he said the United States and other parties will continue to work to "understand the data more thoroughly."
 The authorities have used a series of stransmisi between aircraft and satellite communications to determine that the jet crashed in a remote area of ​​the Indian Ocean. But the plane was not being found.
 Authorities in Malaysia, with British company Inmarsat, this week has released the raw satellite data used narrow the search.
