FBI checking hard drive of pilot's simulator
Missing flight simulator data probed in Malaysia Flight 370 disappearance
(CNN) -- Investigators looking at the flight simulator taken from the home of Malaysia Airlines Flight 370 Captain Zaharie Ahmad Shah have discovered that some data had been erased from it, Malaysia's acting transportation minister said Wednesday.
Hishammuddin Hussein
didn't say what had been deleted, but simulation programs typically
store data from previous sessions for later playback. He also did not
say who might have deleted the data.
The deletions are not
necessarily evidence of ill intent: Removing files from a computer is
usually an innocent act repeated millions of times a day around the
world.
But experts consulted by
CNN said it's relatively unusual to delete such data from a simulator:
The files are extremely small and are often kept by desktop pilots to
gauge their progress, said Jay Leboff, owner of HotSeat, a simulator
manufacturer.
"It would be suspicious to me, because there's no need to do it," he said.
Experts are examining the
simulator in hopes of recovering the deleted data, Hishammuddin said. A
law enforcement source told CNN Wednesday that the Federal Bureau of
Investigation is examining the hard drive.
The revelation came as the search for the missing airliner neared its 13th day.
Although the search area
spans a vast area of nearly 3 million square miles, a U.S. government
official familiar with the investigation said the plane is most likely
somewhere on the southern end of the search area.
"This is an area out of
normal shipping lanes, out of any commercial flight patterns, with few
fishing boats, and there are no islands," the official said, warning
that the search could well last "weeks and not days."
The official's comments
echo earlier analysis by U.S. officials saying the most likely location
for the missing aircraft is on the bottom of the Indian Ocean.
Australia said Wednesday
that the area of the southern Indian Ocean where it is searching for
the plane has been "significantly refined."
The new area is based on
work done by the U.S. National Transportation Safety Board on "the fuel
reserves of the aircraft and how far it could have flown," said John
Young of the Australian Maritime Safety Authority.
But Australian ships and aircraft have so far seen nothing connected to the missing plane, Australian authorities said.
Angry families
The lack of progress has angered and frustrated families, who have accused Malaysian officials of withholding information.
Some family members staged a protest at the hotel where media covering the search are staying.
"We have been here for
10 days, no single piece of information," one woman said. "We need media
from the entire world (to) help us find our lost families, and find the
MH370 plane."
Malaysian authorities appeared to hustle the women away.
In a statement, Hishammuddin said Malaysian authorities "regret the scenes at this afternoon's press conference."
"One can only imagine
the anguish they are going through," he said of the families. "Malaysia
is doing everything in its power to find MH370 and hopefully bring some
degree of closure for those whose family members are missing."
An abrupt change in direction
The plane's
disappearance continues to intrigue the public and frustrate officials,
who have turned up no sign of the plane despite the involvement of teams
from 26 nations.
On Tuesday, a law
enforcement official told CNN that the aircraft's first major change of
course -- an abrupt westward turn that took the plane off its route to
China and back across the Malay Peninsula -- was almost certainly
programmed by somebody in the cockpit.
The change was entered
into the plane's system at least 12 minutes before a person in the
cockpit, believed to be the co-pilot, signed off to air traffic
controllers.
Some experts said the
change in direction could have been part of an alternate flight plan
programmed in advance in case of emergency; others suggested it could
show something more nefarious was afoot.
But Hishammuddin said
Wednesday that "there is no additional waypoint on MH370's documented
flight plan, which depicts normal routing all the way to Beijing."
The Thai military,
meanwhile, said it had spotted the plane turning west toward the Strait
of Malacca early on March 8. That supports the analysis of Malaysian
military radar that has the plane flying out over the Strait of Malacca
and into the Indian Ocean.
But it didn't make it
any clearer where the plane went next. Authorities say information from
satellites suggests the plane kept flying for about six hours after it
was last detected by Malaysian military radar.
Malaysian authorities,
who are coordinating the search, say the available evidence suggests the
missing plane flew off course in a deliberate act by someone who knew
what they were doing.
Background checks
Investigators are
looking into the background of all 239 passengers and crew members on
board the plane, as well as its ground crew, Malaysian officials have
said. They've received background checks on all nations with passengers
on board with the exception of Russia and Ukraine, Hussein said.
So far, no information of significance has been found about any passengers, Hishammuddin said.
China says it has found
nothing suspicious during background checks on its citizens on the
flight -- a large majority of the plane's passengers.
Particular attention has
focused on the pilot and first officer on Flight 370, but authorities
are yet to come up with any evidence explaining why either of them would
have taken the jetliner off course.
And some experts have warned against hastily jumping to conclusions about the role of the pilots.
"I've worked on many
cases were the pilots were suspect, and it turned out to be a mechanical
and horrible problem," said Mary Schiavo, a CNN aviation analyst and
former inspector general for the U.S. Department of Transportation. "And
I have a saying myself: Sometimes, an erratic flight path is heroism,
not terrorism."
Ticking clock
Searchers are racing the
clock in their efforts to find the plane and its flight-data and
cockpit-voice recorders. The devices have batteries designed to send out
pings for 30 days. That leaves 18 days until the batteries are expected
to run out.
Investigators hope the recorders may reveal vital information about why the passenger jet disappeared.
"The odds of finding the
pinger are very slim," said Rob McCallum, an ocean search specialist.
"Even when you know roughly where the target is, it can be very tricky
to find the pinger. They have a very limited range."
Searchers face deep ocean
Hishammuddin, Malaysia's
public face of the search efforts, has repeatedly said that little is
likely to be established about the mysterious flight until the plane is
found.
But in the Indian Ocean,
where Australia and Indonesia have taken the lead in the hunt, some of
the depths that searchers are dealing with are significant.
The Bay of Bengal, for
example, which lies between Myanmar and India, has depths of between
about 4,000 and 7,000 meters (13,000 feet and 23,000 feet), according to
McCallum.
Wreckage and bodies of
passengers from Air France Flight 447, which crashed into the Atlantic
Ocean in 2009, were found at depths of around 12,000 feet by unmanned
submarines.
It took four searches
over the course of nearly two years to locate the bulk of the wreckage
and the majority of the bodies of the 228 people on board Flight 447. It
took even longer to establish the cause of the disaster.
Right now, authorities don't even know for sure if the missing Malaysian plane crashed or landed -- or where.
CNN has talked to more
than half a dozen U.S. military and intelligence officials who emphasize
that while no one knows what happened to the plane, it is more logical
to conclude it crashed into the Indian Ocean.
Examining The Latest Theory On MH370
Update 8.30am ET: The Maldivian government issued a statement
saying that the country's military and airport radars had not seen the
flight. However, it should be noted that a large airplane, by flying at
low level, could easily escape detection by radar.
According to a local newspaper, residents of a remote island in the Maldives, Kuda Huvadhoo, spotted a plane
at 6:15 a.m. local time on March 8 that could have been the missing
Malaysia Airlines 370. Eyewitnesses cited by the paper said they saw "a
jumbo jet," white with red stripes across it, flying low and very
loudly. The description of a big airplane in those colors is consistent
with the Malaysian Boeing 777.
The islanders said they did not recall ever seeing an airplane there,
and at that height, before, making it unlikely that what they had seen
was a normal takeoff or landing by another passenger jet.
6:15 a.m. in the Maldives is 9:15 a.m. in Malaysia, so the sighting
would have occurred seven hours and 45 minutes after the last radio
contact, the now-famous "All right, goodnight" at 1:30 a.m. Malaysian
time over the Gulf of Thailand.
A 777 series 200ER, with a nearly full load of 227 passengers and 12
crew, cargo, and fuel for the scheduled five and a half hour trip from
Kuala Lumpur to Beijing, plus reserves, would typically be able to stay
in the air for a maximum of about eight hours. That makes the presence
of the aircraft at 6 in the morning local time in the middle of the
northern Indian Ocean technically possible.
In fact, the distance between the point of last radio contact and
Kuda Huvadhoo is 2,000 miles, which a 777 at cruise speed would cover in
far less time. Flying in a straight line from the Gulf of Thailand,
MH370 would have appeared over the island no later than 3 a.m. local
time, well before sunrise.
But the plane may not have flown in a straight line, for whatever
reason: possibly a hijacking, and maybe the crew's attempt to foil it.
Or it may have flown at very low level to avoid detection, where the air
is thicker and jet planes fly slower because of added drag. It may also
have been flying at reduced speed to conserve fuel, either because
whoever controlled the plane wanted to maximize its range, or because
jet engines are less efficient at low altitude.
One thing the Maldivian eyewitnesses did not mention, at least in the
local newspaper's account, is seeing signs of the onboard fire that
some experts say could have incapacitated or killed the crew while the
plane kept flying on autopilot.
The idea of a fire as cause for MH370 crashing was first floated by a pilot
on Google Plus last weekend, and went viral. It rests on the assumption
that the pilots, far from being in on some nefarious plot, were heroes
who steered the plane toward the most convenient airport for an
emergency landing as soon as they realized that they had a fire or some
other grave problem.
That airport would have been on the island of Langkawi off the west
coast of Malaysia, exactly on the compass heading that the plane took
when it turned westward over the South China Sea. Then the crew
succumbed to the fire, or to lack of oxygen, and the plane kept flying
on autopilot until fuel ran out.
But the fire plus emergency diversion theory, as compelling as it is
and similar to other known incidents, leaves one question unanswered. If
the pilots tried for a landing at Langkawi and missed because they
became incapacitated, the autopilot would have kept them flying straight
and level on the last compass heading. (Which would have taken MH370
more or less over Kuda Huvadhoo, by the way.)
Yet we know from Malaysian military radar tracking
that after passing the west coast of Malaysia, MH370 zigzagged north
and west, toward the Andaman Islands, following precise waypoints.
Shortly before reaching the Andamans, it was lost to radar, and might
have possibly made the Maldives, before disappearing toward one of the
two arcs -- one in Central Asia, the other off the west coast of
Australia -- where satellite pings say it must have ended its flight.
So,
either someone was entering those waypoints in the flight management
computers, or the computers had been programmed earlier to send the
plane there. The former option is not consistent with an unconscious or
dead crew. The latter makes no sense for a crew in a dire emergency,
looking for the closest place to land -- unless one wants to believe the
improbable and now-debunked scenario that hackers were steering the
plane.
If the Maldivian sighting is not a false lead, then, it lends
strength to the theory that MH370 must have ditched or crashed in the
ocean.
It did not land at the airport of the Maldives' capital Male, and the
closest airport big enough for a 777, Mahe in the Seychelles Islands,
1,400 miles away, hasn't seen the missing jet, which could not have had
enough fuel to get there anyway if it really overflew Kuda Huvadhoo when
the eyewitnesses said it did. The U.S. and British airbase at Diego
Garcia is closer, 800 miles away, and also has a runway long enough for
the jet, but has not reported sighting the aircraft either.
As for the coast of Africa, lawless Somalia, an ideal place for a
hijacked plane to land, is 2,000 miles from the Maldives. That would
have been too far for Malaysian 370, and was also likely among the first
places that spy satellites would have scoured for signs of a giant,
easily visible airplane, which they did not see. And as Wednesday dawned
in Malaysia, neither had anyone else, for the eleventh day since the
mystery began.
