New missing Malaysian plane MH370 search area announced

A new search area for the missing Malaysian plane has been announced by the Australian government after further analysis of satellite data.

The search will now shift south to focus on an area 1,800km (1,100 miles) off the west coast of Australia, Deputy Prime Minister Warren Truss confirmed.

Flight MH370 vanished en route from Kuala Lumpur to Beijing on 8 March with 239 passengers on board.

Officials said they believed the plane had been on autopilot when it crashed.

A 64-page report released by the Australian government concluded that the underwater search for the plane should resume in the new 60,000 sq km area.

An extensive search of the ocean floor was conducted in April after several acoustic pings, initially thought to be from the plane's flight data recorders, were heard. However, officials now believe the pings were not caused by the plane.



"It is highly, highly likely that the aircraft was on autopilot otherwise it could not have followed the orderly path that has been identified through the satellite sightings," Mr Truss said.
Analysis:
The new search area focuses on the "7th arc" - a line through which the analysis suggests the jet had to have crossed as it made a final, brief, connection with ground systems. The interpretation of the data is that this "electronic handshake" was prompted by a power interruption onboard MH370 as its fuel ran down to exhaustion. As power came back on, the jet tried to log back into the satellite network.

My sources tell me that following that logon request there would normally have been additional "chatter" between the network and MH370. That these connections are not seen in the data log are a very strong indication that the jet was heading down.

Several teams within the investigation have been running the numbers; this is not the sole work of the satellite system's operator - Inmarsat.

The collective opinion of several independent teams has therefore arrived at a zone of highest probability covering some 60,000 sq km. Once the ocean floor there is mapped, the investigation team can then summon the best - but also the most appropriate - submersibles in the world to go hunt for sunken wreckage.
Expensive search
The underwater search for the plane was put on hold to allow more time for survey vessels to map the ocean floor.

The new search is due to commence in August and is expected to be completed within a year, Australian Transport Safety Bureau (ATSB) chief Martin Dolan confirmed.

Submarines will scour the ocean floor to look for signs of the missing Boeing 777. The area has already been searched by air, and officials say any floating wreckage will have sunk to the ocean floor.

Several teams working independently of each other have reached similar conclusions relating to the new search area, the reporters says.

The search for the missing airliner is already among most expensive in aviation history.

After more than 100 days since the disappearance of the airliner, many of the relatives of the missing passengers have continued to express frustration at the lack of progress in the search.
