Ships and
aircraft criss-crossed the seas off Borneo on Friday hunting for the
wreck of an Indonesia AirAsia passenger jet, but bad weather again
hindered the search for the plane and the black box flight recorders
that should reveal why it crashed.
An official said 30 bodies had
been recovered, along with pieces of the broken-up plane, in the
Indonesian-led search for Flight QZ8501 that is concentrated on 1,575
square nautical miles of the northern Java Sea.
Strong
winds and heavy seas have stopped divers from looking for the fuselage
of the Airbus A320-200, which plunged into the water on Sunday while en
route from Indonesia's second-biggest city Surabaya to Singapore with
162 people on board.
"Waves were
between 3 and 4 meters today, making it difficult to load bodies onto
ships and between ships," Fransiskus Bambang Soelistyo, head of
Indonesia's search and rescue agency, told reporters in Jakarta, adding
that some vessels would search through the night.
"Tonight we are sending tug boats which should make the (body) transfers easier."
He said two of the 30 bodies found were strapped to their plane seats.
The
multinational search operation based in Pangkalan Bun, the town in
southern Borneo closest to the search area, was bolstered on Friday by
experts from France's BEA accident investigation agency, which attends
all Airbus crashes.
Officials said
the French team's hydrophones - sophisticated underwater acoustic
detection devices - and towed sonar equipment brought by other
international experts could not be used on Friday because of high waves.
But
naval vessels from Indonesia, the United States and Singapore with
in-built anti-submarine capabilities were using sonar to sweep the sea
floor.
STALL THEORY
The
cause of the crash, the first suffered by the AirAsia group since the
budget operator began flying in 2002, is unexplained. Investigators are
working on a theory that the plane stalled as it climbed steeply to
avoid a storm about 40 minutes into a flight that should have lasted two
hours.
Officials earlier said it
may take up to a week to find the black boxes, which investigators hope
will unravel the sequence of events in the cockpit during the doomed
jet's final minutes.
"After the
black box is found, we are able to issue a preliminary report in one
month," said Toos Sanitioso, an investigator with the National Committee
for Transportation Safety. "We cannot yet speculate what caused the
crash."
Even in bad weather, the
search for the AirAsia plane is less technically challenging than the
two-year search for an Air France jet that crashed into deep Atlantic
waters in 2009, or the fruitless hunt for Malaysia Airlines Flight MH370
that disappeared last year.
Given
Flight QZ8501 crashed in shallow seas, experts say finding the boxes
should not be difficult if its locator beacons, with a range of 2,000 to
3,000 meters (6,560 to 9,800 ft) and a battery life of about 30 days,
are working.
Bodies plucked from
the sea are being taken in numbered coffins to Surabaya, where relatives
of the victims, most of whom were Indonesian, have gathered.
Authorities have been collecting DNA from relatives to help identify the
bodies.
The first funeral of one
of the crash victims was held on Thursday, and on Friday officials said
the remains of three more had been identified, including a flight
attendant.
AirAsia boss Tony Fernandes tweeted that he would accompany the body of one victim home from Surabaya.
"I'm arriving in Surabaya to take Nisa home to Palembang," he wrote. "I cannot describe how I feel. There are no words."
"UNBELIEVABLY" STEEP CLIMB
The
plane was traveling at 32,000 ft (9,753 meters) and the pilots had
asked to climb to 38,000 ft to avoid bad weather just before contact was
lost. When air traffic controllers granted permission to fly at 34,000
ft a few minutes later, they got no response.
A
source close to the investigation said radar data appeared to show the
aircraft made an "unbelievably" steep climb before it crashed, possibly
pushing it beyond the A320's limits.
Hadi
Mustofa Djuraid, a Transport Ministry official, told reporters that
authorities were investigating the possibility that the pilot did not
ask for a weather report from the meteorological agency at the time of
takeoff.
He added that pilots were required to do so before flying.
Indonesia
AirAsia's president director, Sunu Widyatmoko, said in a text message:
"We will make a release shortly" on that aspect of the investigation.
The
Indonesian captain, a former air force fighter pilot, had 6,100 flying
hours on the A320 and the plane last underwent maintenance in
mid-November, according to Indonesia AirAsia, 49 percent owned by
Malaysia-based AirAsia.
Three airline disasters involving Malaysian-affiliated planes in under a year have spooked travelers.
Malaysia
Airlines Flight MH370 disappeared in March en route from Kuala Lumpur
to Beijing with 239 passengers and crew and has not been found. On July
17, the same airline's Flight MH17 was shot down over Ukraine, killing
all 298 people on board.
On board
Flight QZ8501 were 155 Indonesians, three South Koreans, and one person
each from Singapore, Malaysia and Britain. The co-pilot was French.
