Chinese relatives furious as robo submarine fails to find clues of missing MH370

As US Navy's robotic submarine dove into the Indian ocean to search for clues for lost Flight MH370, angry Chinese relatives stormed out of a teleconference meeting to protest against the Malaysian government for not addressing them in person.

The Bluefin-21 sub surfaced for the second time after experiencing technical difficulties.

According to news.com.au, Australian-led Joint Agency Coordination Centre said it was sent back into the water after its data was downloaded but there's been no sign of the plane.

However, experts are increasingly confident authorities are searching in the right place.

As the search continued, more than 100 relatives of Chinese passengers on the plane walked out of a teleconference meeting with senior Malaysian officials.

The move was an act of defiance over a lack of contact with that country's government and for taking so long to respond to their demands.

The family members had gathered in a meeting room at a Beijing hotel where Malaysia Airlines had provided lodging and food, the report added.
