For relatives of those aboard the plane, hope was slipping away, said Nan Jinyan, sister-in-law of passenger Yan Ling.
“I’m psychologically prepared for the worst and I know the chances of them coming back alive are extremely small,” said Nan, one of dozens of relatives gathered at a Beijing hotel awaiting any word about their loved ones.
The Norwegian cargo vessel Hoegh St. Petersburg is also in the area helping with the search. Haakon Svane, a spokesman for the Norwegian Shipowners’ Association, said the ship had searched a strip of ocean stretching about 100 nautical miles (115 miles; 185 kilometers).
The Australian Maritime Safety Authority said another commercial ship also was in the area, and an Australian navy vessel was en route. AMSA officials also were checking to see if there was any new satellite imagery that could provide more information.
Aircraft pieces have sometimes been found floating for days after a sea crash. Peter Marosszeky, an aviation expert at the University of New South Wales, said the wing could remain buoyant for weeks if fuel tanks inside it were empty and had not filled with water.
Other experts said that if the aircraft breaks into pieces, normally only items such as seats and luggage would remain floating.
“We seldom see big metal (pieces) floating. You need a lot of (buoyant) material underneath the metal to keep it up,” said Lau Kin-tak, an expert in aircraft maintenance and accidents at Hong Kong Polytechnic University.
Flight 370 relatives met Friday with Malaysian officials at the Beijing hotel. Attendees said they had a two-hour briefing about the search but that nothing new was said.
Wang Zhen, son of missing artist Wang Linshi, said there were questions about why Malaysian authorities had provided so much seemingly contradictory information.
Wang said he still has hopes his father can be found alive and is praying that the satellite sightings turn out to be false. He said he and other relatives are suspicious about what they are being told by the Malaysian side but are at a loss as to what to do next.
