Air Force planes took to the skies in search of a missing jetliner and navy ships scoured the sea Wednesday, one day after senior Indonesian officials wrongly said the Boeing 737's wreckage had been found and a dozen people survived.
Forecasts of heavy storms, meanwhile, were threatening rescue efforts already hampered by a potentially damaged emergency locator, remote mountainous terrain and choppy waters.
"Until now, we have not yet found any signal or indication of where the ill-fated plane crashed," Air Force official Eddy Suyanto, the search mission coordinator, told The Associated Press.
Three navy ships set sail soon after sunrise in the Makkasar Strait and five Air Force planes took to the skies, searching for signs of the Adam Air plane, said Bambang Karnoyudho, the head of the National Search and Rescue Agency.
But as nightfall approached, nothing had been found, officials said, preparing to continue with a land and sea search early Thursday.
"God willing, we can find it soon," Karnoyudho told The Associated Press.
The Adam Air plane carrying 102 people was flying from Indonesia's main island of Java to North Sulawesi's provincial capital of Manado when it disappeared Monday in stormy weather after sending out distress signals - one over mountainous jungles and the other along the coast.
Rescue teams spent more than 10 hours Tuesday hiking through slippery forest paths in a mountainous region of Sulawesi's western coast but found nothing, prompting authorities to expand their search on Wednesday.
Karnoyudho said based on radar and satellite readings he thought it most likely that the Adam Air plane had fallen into the sea.
Air Force Squadron Commander Lt. Col. Mudjianto, whose team followed the plane's scheduled flight path to the site where its last distress signal was picked up, said visibility was good Wednesday as his team searched a roughly 300-square-mile (yard) triangle of sea and land.
"We flew over the area four times ... but there was no sign of the plane," Mudjianto said.
Relatives of the passengers - some camped out at the Adam Air counter at the Manado airport - were losing patience after being misinformed one day earlier about the fate of the plane.
Top Indonesian aviation, military and police officials - and the airline itself - had said the plane had been found in a remote part of Sulawesi. They said that 90 people on board had perished, but that the remaining 12 may have survived.
Descriptions were vivid, with officials saying corpses and debris from the plane were scattered over a 300-meter (327-yard) area of forest and jagged cliffs - highlighting the often unreliable and chaotic nature of disaster relief efforts in the world's largest archipelagic nation.
Aviation experts say the vast area the aircraft may have gone down in; the dense, remote island terrain; and a potentially damaged emergency locator beacon may further slow search operations.
"In an area of low population density, particularly if it is in inhospitable terrain - such as jungle, or a deep ravine or covered by a canopy - it could sit for a long time without being found," said Laurence Benn, head of the Center for Civil Aviation in London.
Eventually, Transport Minister Hatta Radjasa acknowledged the news that the plane had been located was based on rumors from villagers, sparking a series of reversals from other officials.
"I don't understand how the authorities could be so heartless and spread rumors without thinking of the suffering of those waiting for news of their loved ones," said Ima Kulata, who was awaiting word about her cousin and two nieces.
"It's ridiculous," she said, crying after learning there may be no survivors after all. "How come they make such fools of us?"
Three of those aboard were American citizens, the U.S. Embassy said. A U.S. National Transportation Safety Board team was to arrive Friday to offer assistance. It was unclear whether any other foreigners were on the plane.
