Two objects spotted in the southern Indian Ocean may be debris from the missing Malaysia Airlines Flight 370, Australian authorities said Thursday, fueling hopes of a breakthrough in an international search of unprecedented scale.

周四澳大利亚官方称，在南印度洋发现的疑似碎片可能是马航失联客机MH370的残骸。这一发现给全球空前大搜索带来突破性希望。

The objects are indistinct but of "reasonable size," with the largest about 24 meters (79 feet) across, said John Young, general manager of emergency response for the Australian Maritime Safety Authority.

澳大利亚海洋安全局应急总指挥约翰·杨说，两块物件不是很清楚，但尺寸十分吻合。

They appear to be "awash with water and bobbing up and down" in an area 2,500 kilometers (1,500 miles) southwest of Australia's west coast, he said.

他补充道，看上去两块物件好像在澳大利亚2500平方公里的西南海域内上下浮动，被海浪冲刷。

"If that piece of the plane is that big, maybe it's the tail section" said David Gallo, one of the leader of the search for Air France Flight 447, which crashed in the Atlantic Ocean in 2009.

曾经共同领导2009年法航447航班搜寻的大卫·加洛说，“考虑到马航失联客机机型庞大，这些疑似碎片有可能是机尾部分。” 法航447在2009年坠落在大西洋。

The tail height of a Boeing 777, the model of the missing Malaysian plane, is 60 feet.
