REPUBLIKA.CO.ID, KUALA LUMPUR/PERTH - China said on Saturday it had a new satellite image of what could be wreckage from a missing Malaysian airliner, as more planes and ships headed to join an international search operation scouring some of the remotest seas on Earth.
The latest possible lead came as the search for Malaysian Airlines Flight MH370 entered its third week, with still no confirmed trace found of the Boeing 777 or the 239 people on board.
The new potential sighting was dramatically announced by Malaysia's acting transport minister, Hishammuddin Hussein, after he was handed a note with details during a news conference in Kuala Lumpur, scooping the official announcement from China.
"Chinese ships have been dispatched to the area," Hishammuddin told reporters.
China said the object was 22 metres long (74ft) and 13 metres (43ft) wide, and spotted around 120 km (75 miles) "south by west" of potential debris reported by Australia off its west coast in the forbidding waters of the southern Indian Ocean.
The image was captured by the high-definition Earth observation satellite "Gaofen-1" early on March 18, two days after the Australian satellite picture was taken, China's State Administration of Science, Technology and Industry for National Defense (SASTIND) said on its website.
It could not easily be determined from the blurred images whether the objects were the same, but the Chinese photograph could depict a cluster of smaller objects, a senior military officer from one of the 26 nations involved in the search for the plane said.
The wing of a Boeing 777-200ER is approximately 27 metres long and 14 metres wide at its base, according to estimates derived from publicly available scale drawings. Its fuselage is 63.7 metres long by 6.2 metres wide.
Flight MH370 vanished from civilian radar screens early on March 8, less than an hour after taking off from Kuala Lumpur on a scheduled flight to Beijing.
China said its icebreaker "Snow Dragon" was heading for the area, but was still around 70 hours away. Japan and India were also sending more planes and Australian and Chinese navy vessels were steaming towards the southern search zone.
But the area is known for rough seas and strong currents, and Malaysia's Hishammuddin said a cyclone warning had been declared for Christmas Island, far off to the north.
"There are vessels heading in that direction. They may have to go through the cyclone," he said.
Since Australia announced the first image of what could be parts of the aircraft on Thursday, the international search for the plane has focused on an expanse of ocean more than 2,000 km (1,200 miles) southwest of Perth.
