Aircraft and ships ploughed through dire weather on Thursday in search of objects floating in remote seas off Australia that Malaysia’s government called a “credible lead” in the trans-continental hunt for a jetliner missing for nearly two weeks.

The large objects, which Australian officials said were spotted by satellite four days ago in one of 
the remotest parts of the globe, 
are the most promising find in 
days as searchers scour a vast 
area for the plane lost with 239 people on board.

A Norwegian merchant ship arrived in the area on Thursday, but officials cautioned it could take days to confirm if the objects were parts of the Malaysia Airlines Boeing 777. Malaysia’s government said the search would continue elsewhere despite the sighting in the southern Indian Ocean.

The area where the objects were spotted is around 2,500km southwest of Perth, roughly corresponding to the far end of a southern track that investigators calculated the aircraft could have taken after it was diverted.

“Yesterday I said that we wanted to reduce the area of the search. We now have a credible lead,” Malaysian Transport Minister Hishammuddin Hussein told reporters in Kuala Lumpur.

“There remains much work to be done to deploy the assets. This work will continue overnight.”

A search for the plane that began in the tropical waters off Malaysia’s east coast has now switched to 
the vast, icy southern oceans between Australia, southern Africa and Antarctica.

There have been many false leads and no confirmed wreckage found from Flight MH370 since it vanished from air traffic control screens off Malaysia’s east coast early on March 8, less than an hour after taking off from Kuala Lumpur for Beijing.

Hishammuddin said the information on the objects received from Australia had been “corroborated to a certain extent” by other satellites, making it more credible than previous leads.

The larger of the objects measured up to 24 metres, long and appeared to be floating in water several thousand metres deep, Australian officials said. The second object was about five metres long. Arrows on the images pointed to two indistinct objects apparently bobbing in the water.

“It’s credible enough to divert the research to this area on the basis it provides a promising lead to what might be wreckage from the debris field,” Royal Australian Air Force Air Commodore John McGarry said in Canberra. The satellite images, provided by US company DigitalGlobe , were taken on March 16, meaning that the possible debris could by now have drifted far from the original site.

Australian officials said an aircraft had dropped a series of marker buoys in the area, which will provide information about currents to assist in calculating the latest location. The captain of the first Australian air force AP-3C Orion plane to return from the search area described the weather conditions as “extremely bad” with rough seas and high winds.

“The weather conditions were such that we were unable to see for very much of the flight today but the other aircraft that are searching, they may have better conditions,” Flight Lieutenant Chris Birrer said.

At least one aircraft, a Royal New Zealand Air Force Orion, was still in the search area, while other aircraft including a US Navy P-8 Poseidon were returning to Perth, according to the Australian Maritime Safety Authority (AMSA).

A Norwegian car carrier diverted from its journey from Madagascar to Melbourne and had arrived in the search area, the ship’s owner said. A Royal Australian Navy ship equipped to recover any objects was also en route. China’s icebreaker for Antarctic research, Xuelong, or Snow Dragon, will set off from Perth to search the area, Chinese state news agency Xinhua cited maritime authorities as saying. About two-thirds of the 227 passengers on Flight MH370 were Chinese nationals.

Investigators believe that someone with detailed knowledge of both the Boeing 777-200ER and commercial aviation navigation switched off the plane’s communications systems before diverting it thousands of miles off its scheduled course.

Exhaustive background checks of the passengers and crew aboard have yielded barely anything that might explain why.

The discovery of the floating objects was revealed by Australian Prime Minister Tony Abbott.

“The task of locating these objects will be extremely difficult and it may turn out they are not related to the search for MH370,” he told parliament.

The dimensions of the objects given are consistent with at least one of them possibly being the major part of a 777-200ER wing, which is around 27 metres long, though Australian officials cautioned the first images were indistinct.

The relatively large size of the objects would suggest that, if they do come from the missing aircraft, it was largely intact when it went into the water.

If the plane had run out of fuel, it would not necessarily have plummeted but its behaviour would have depended on whether there was someone in control and their intentions, pilots said.

Modern aircraft are designed to use the rush of wind to drive a 
small emergency turbine that keeps hydraulics and some electrical power running if the engines run out of fuel.

If the debris is from the plane, investigators would face a daunting task to retrieve the “black box” data and voice recorders needed to help understand what caused the disaster.

University of Western Australia Professor of Oceanography Charitha Pattiaratchi said that, based on currents in the area, if the debris is from the plane it probably would have entered the water around 300-400km to the west.

The search area covered an ocean ridge known as Naturalist Plateau, a large sea shelf about 3,500 metres deep, Pattiaratchi said. The plateau is about 250km wide by 400km long, and the area around it is close to 5,000 metres deep.
