Pilot Spoke to Air Controllers After Shutoff of Data System
International New York Times | 16 March 2014
SEPANG,
Malaysia — A signaling system was disabled on the missing Malaysia
Airlines jet before a pilot spoke to air traffic control without
mentioning trouble, a senior Malaysian official said on Sunday,
reinforcing theories that one of the pilots may have been involved in
diverting the plane and adding urgency to the investigation of their
pasts and possible motivations.
With
the increasing likelihood that Flight 370 was purposefully diverted and
flown possibly thousands of miles from its planned route, Malaysian
officials faced more questions about how the investigation, marked by
days of contradictory government statements, might have ballooned into a
global goose chase for information.
Prime
Minister Najib Razak acknowledged on Saturday that military radar and
satellite data raised the possibility that the plane could have ended up
somewhere in Indonesia, the southern Indian Ocean, or along a vast arc
of territory from northern Laos across western China to central Asia.
Malaysian officials said they were scrambling to coordinate a 25-nation
effort to find the plane.
Commercial
passenger planes use radio or satellite signals to send data through
ACARS, the Aircraft Communications Addressing and Reporting System. The
system can monitor engines and other equipment for problems that may
need attention when a plane lands.
Although
officials had already said that ACARS was disabled on the missing
plane, it had previously been unclear whether the system stopped
functioning before or after the captain radioed his last, brief words to
Kuala Lumpur, in which he did not indicate that anything was wrong with
the signaling system or the plane as a whole.
During
a news conference on Sunday, the defense minister, Hishammuddin
Hussein, who is also acting minister of transportation, gave a terse
answer: “Yes, it was disabled before,” he said.
The
fate of the plane and the people it carried has become a formidable
riddle, bringing together questions about aviation technology,
investigation of the private lives of passengers and crew, and a search
across a vast arc of the Indian Ocean and often rugged, remote terrain
in Asia, with no clear idea of where to begin.
“It’s
something of the scope I’ve never seen before,” Cmdr. William Marks,
the spokesman for the United States Navy Seventh Fleet, which sent two
guided-missile destroyers to join the search, said in a telephone
interview. Of the size of the Indian Ocean, he said: “Essentially, it’s
like looking for a person somewhere between New York and California.
It’s that big.”
Malaysian
officials on Sunday briefed representatives from 22 countries in the
region and beyond that could help search along the two corridors where
satellite data indicate the plane may have wound up, having flown up to
six hours after its disappearance beyond the range of military radar in
western Malaysia. Mr. Hishammuddin said Malaysia would also ask the
United States, China, France and other countries to provide satellite
data.
But
establishing what happened to the plane also depends on reconstructing
events in the cockpit in the early-morning moments on March 8 when the
jet was passing over the Gulf of Thailand between northern Malaysia and
southern Vietnam. At that time, its communications links were severed
and it changed direction, flying across the Malaysian peninsula and out
over the Strait of Malacca.
Given
the complexity of that feat, experts and American government officials
say that experienced aviators, possibly one or both of the pilots, were
probably involved, either willingly or under coercion.
The
plane’s transponder, which sends tracking signals to air traffic
controllers, was disabled at 1:21 a.m., about a dozen minutes after
ACARS was disabled, making it difficult to monitor the plane’s movements
through the usual means.
Malaysia
Airlines has previously said that the last voice communication with the
plane came around 1:30 a.m. Mr. Hishammuddin was not asked and did not
say whether that communication came after the disabling of the
transponder as well as of ACARS.
The plane’s disappearance has prompted speculation, so far unproven, about involvement by extremists.
The
Malaysian authorities trying to locate Flight 370 have not singled out
the pilots or crew as the only potential suspects. Officials said on
Sunday that they would scrutinize the backgrounds of all 239 passengers
and crew onboard, as well as ground crew and engineers who worked on the
Boeing 777 jet, which took off at 12:41 a.m. local time on March 8.
“The
Malaysian authorities are refocusing their investigation on all crew
and passengers,” Mr. Hishammuddin said. “I understand the hunger for new
details, but we do not want to jump to conclusions.”
According
to the airline, he said, “the pilot and co-pilot did not ask to fly
together on MH370.” If true, that point might undermine speculation that
the two men acted in unison in the plane’s disappearance.
Mr.
Hishammuddin confirmed that the Malaysian police had searched the Kuala
Lumpur homes of the captain and co-pilot on Saturday. The police took
to their offices a flight simulator the pilot, Mr. Zaharie, had kept at
his home, and reassembled it so that experts could examine its workings,
Khalid Abu Bakar, the inspector general of the Malaysian police, told
reporters.
Rohan
Gunaratna, a professor at Nanyang Technological University in Singapore
who studies security and terrorism in Asia, said that while the weight
of suspicion would inevitably fall on the pilots and other crew members,
investigators were following established procedure by examining
everyone on the missing plane.
Soon
after the plane disappeared, F.B.I. agents and other American
investigators “scrubbed” the names of the pilots and passengers,
including two Iranian men who traveled on stolen passports, to determine
whether they had any connections to terrorists. They have found no such
connections, officials said on Sunday, while cautioning that the home
countries of some of the passengers had not yet supplied full background
checks on their citizens who were aboard the plane.
“You
can’t rule anything out, so everyone on the plane must be treated as a
potential suspect,” Professor Gunaratna said in a telephone interview.
He said he had heard no credible information of any militant group’s
claiming responsibility for seizing the plane.
“That
does not mean the possibility does not exist, but at this stage of the
investigation it’s important to be open to all the possibilities,” he
said.
As
investigators dug into the backgrounds of the people aboard Flight 370,
the families of the pilot and first officer kept a low profile on
Sunday and issued no statements.
In
the upscale western suburbs of Kuala Lumpur where both men live, a
near-permanent daytime encampment of local and foreign journalists had
taken root outside their homes.
Neighbors
said that Mr. Fariq was the eldest of five children and that the family
had moved to the neighborhood, a quiet residential section of the Shah
Alam suburb popular with faculty members from a nearby university, about
a decade ago. Residents said the family was kind, decent and pious.
Mr.
Fariq’s father, a senior official in the federal public works
department, was a regular worshiper at the mosque at the end of the
block, neighbors said; Mr. Fariq, the eldest of three sons and two
daughters, attended less frequently because he was often out of town on
trips with the airline.
“He’s
a very nice man,” Ayop Jantan, a retiree who lives two doors down from
the family, said of Mr. Fariq. “When he comes back with his luggage, he
greets me like an uncle.”
Even
knowing where to restart the search for the plane is difficult. Until
Mr. Najib’s dramatic announcement about the likely course of the plane,
many aircraft and ships were devoted to scanning the seas off Malaysia’s
east coast — precisely the opposite direction from the new focus of the
hunt.
“Malaysian
officials are currently discussing with all partners how best to deploy
assets along the two corridors” indicated by satellite data, the
Malaysian transport ministry said in a written statement. “Both the
northern and southern corridors are being treated with equal
importance.”
A
satellite orbiting 22,250 miles over the middle of the Indian Ocean
received the final transmission, which, based on the angle from which
the plane sent it, came from somewhere along one of the two corridors
investigators are exploring.
The
northern arc touches southern Kazakhstan and northern Kyrgyzstan in
central Asia before running across a huge swath of western and
southwestern China, and ending in northern Laos. To reach most of those
areas, the aircraft would have had to traverse heavily militarized areas
in China, India or Pakistan, although it could have tried an end run
across Myanmar.
The
southern corridor, from Indonesia to the southern Indian Ocean, travels
over open water with few islands. If the aircraft took that path, it
might have passed near the Cocos (Keeling) Islands. These remote
Australian islands, with a population of fewer than 1,000 people, have a
small airport.
“It
is a daunting task to even begin to plan how you would search an entire
ocean,” said Commander Marks, the spokesman for the Seventh Fleet.
