The missing AirAsia
Indonesia flight QZ8501 is likely to be at the bottom of the sea, the
head of Indonesia's search-and-rescue agency has said.
Bambang Soelistyo said the hypothesis was based on the co-ordinates of the plane when contact with it was lost.
The search is continuing for the aircraft, a day after it
disappeared with 162 people on board, but no trace has been found so
far.
The Airbus A320-200 was on a flight to Singapore.
The pilots had requested a course change because of bad weather but
did not send any distress call before the plane disappeared from radar
screens.
"Based on the co-ordinates given to us and evaluation that
the estimated crash position is in the sea, the hypothesis is the plane
is at the bottom of the sea," Bambang Soelistyo, the head of Indonesia's
search and rescue agency, told a news conference in Jakarta.
The front page of the Beijing Times says: "Only three days before the New Year - where is the road to home?"
The reactions are similar in Indonesia, Singapore and
Malaysia. Many on board were travelling to see their families for the
year-end holiday season.
Media reports say the families are united in their prayers, hoping against hope for a miracle.
Many newspapers have published personal stories. One that has
moved many people is about the Facebook post from the daughter of one
of the pilots. It simply reads: "Papa come home."
Some are also calling 2014 a "year of tragedies" for the
aviation industry, linking it with the flight MH370 that disappeared in
March and hasn't been found yet.
Beyond the emotional coverage, commentators have been asking questions about aviation safety in the region.
South-East Asia has a fast-developing aviation sector with
many carriers fighting for space, observers say. Most welcome the
competition, but say safety norms have to be strengthened.
As the
search continued on Monday, Indonesia air force spokesman Hadi Tjahnanto
said it was being focused on an area where an oil spill had been
spotted but it was not clear if it had been caused by the plane.
Meanwhile the Associated Press news agency quoted an
Indonesian official as saying that objects had been spotted in the sea
near Nangka island by an Australian search plane.
Indonesian Vice-President Jusuf Kalla said later there was "no sufficient evidence" to link this to the missing plane.
He said that 30 ships and 15 aircraft were taking part in the search, and that "even fishermen" were being asked to join in.
AirAsia's share price fell 7% in morning trading on Monday in Kuala Lumpur.
Storm clouds
Flight QZ8501 had left Surabaya in eastern Java at 05:35 on
Sunday (22:35 GMT Saturday) and was due to arrive in Singapore at 08:30
(00:30 GMT).

The pilot radioed at 06:24 local time asking permission to climb to 38,000ft (11,000m) to avoid the dense storm clouds.
Indonesian
officials said the request could not be immediately approved due to
traffic, but the plane disappeared from the radar screens before the
pilots gave any further response.
AirAsia boss Tony Fernandes said this was his "worst nightmare".
Mr Fernandes flew to Surabaya and later said: "We are very devastated by what's happened, it's unbelievable."
Oceanographer Simon Boxall told the BBC the plane should not be too difficult to find if it went into the water.
The sea floor is within diver depth, he says, and it would be "likely that they'll get answers within a few days".
Difficult year
The AirAsia Indonesia plane was delivered in 2008, has flown
13,600 times, completing 23,000 hours, and underwent its last
maintenance in November.
The captain, Iriyanto, had more than 20,500 flight hours,
almost 7,000 of them with AirAsia, Mr Fernandes said. The co-pilot is
French national Remi Emmanuel Plesel.
The AirAsia group has previously had no fatal accidents
involving its aircraft. The airline has set up an emergency line for
family or friends of those who may be on board. The number is +622 129
850 801.
Special centres were set up at both Singapo
e's Changi airport and Juanda international airport in Surabaya.
There were 155 passengers on board, the company
said in a statement:
- 137 adults, 17 children and one infant
- Most were Indonesian but also one UK national, a Malaysian, a Singaporean and three South Koreans
- The BBC understands that the British national is Chi-Man Choi
- Two pilots and five crew were also on board - one French, the others Indonesian

This has been a difficult year for aviation in Asia -
Malaysia's national carrier Malaysia Airlines has suffered two losses -
flights MH370 and MH17.
Flight MH370 disappeared on a flight from Kuala Lumpur to
Beijing in March with 239 passengers and crew. The wreckage, thought to
be in the southern Indian Ocean, has still not been located.
MH17 was shot down over Ukraine in July, killing all 298 on board.
