SEPANG, Malaysia — Malaysia Airlines Flight 370 experienced significant
changes in altitude after it lost contact with ground control, and altered
its course more than once as if still under the command of a pilot, American
officials and others familiar with the investigation said Friday.
Radar signals recorded by the Malaysian military appear to show the missing
airliner climbing to 45,000 feet, above the approved altitude limit for a
Boeing 777-200, soon after it disappeared from civilian radar and made a
sharp turn to the west, according to a preliminary assessment by a person
familiar with the data.

The radar track, which the Malaysian government has not released but says it
has provided to the United States and China, then shows the plane
descending unevenly to an altitude of 23,000 feet, below normal cruising
levels, as it approached the densely populated island of Penang, one of the
country’s largest. There, the plane turned from a southwest-bound course,
climbed to a higher altitude and flew northwest over the Strait of Malacca
toward the Indian Ocean.

Detecting a Plane
Two kinds of radar are used to keep track of air traffic from the ground.
Primary radar
Sends out radio signals and listens for echoes that bounce back from objects
in the sky.
TRANSPONDER
Secondary radar
Sends signals that request information from the plane’s transponder. The
plane sends back information including its identification and altitude. The
radar repeatedly sweeps the sky and interrogates the transponder. Other
planes in flight can also receive the transponder signals.
THE NEW YORK TIMES
Investigators have also examined data transmitted from the plane’s Rolls-
Royce engines that shows it descending 40,000 feet in the space of a minute,
according to a senior American official briefed on the investigation. But
investigators do not believe the readings are accurate because the aircraft
would likely have taken longer to fall such a distance.
“A lot of stock cannot be put in the altitude data” sent from the engines,
one official said. “A lot of this doesn’t make sense.”
The data, while incomplete and difficult to interpret, could still provide
critical new clues as investigators try to determine what transpired on
Flight 370, which disappeared early last Saturday carrying 239 people from
Kuala Lumpur to Beijing.
Malaysian and international investigators have said in recent days that the
plane may have departed from its northerly flight route toward Beijing and
headed west across the Malaysian peninsula just after it disappeared from
civilian radar, its pilots stopped communicating with ground controllers and
its transponders stopped transmitting data about its speed and location.
The plane is also now thought to have continued flying for more than four
hours after diverting its course, based on automated “pings” sent by
onboard systems seeking to connect with satellites.
But the Malaysian military radar data, which local authorities have declined
to provide to the public, add significant new information about the flight
immediately after ground controllers lost contact. The combination of
altitude changes and at least two significant course corrections could have
a variety of explanations, including an intentional diversion by a pilot or
a hijacker, or uneven flying because a disabled crew.
The erratic movements of the aircraft after it diverted course and flew over
the country also raise questions about why the military did not respond in
real time to the flight emergency. Malaysian officials have acknowledged
that military radar may have picked up the plane, but have said they took no
action because it did not appear hostile.
Seven days after the jet’s disappearance, Malaysian authorities have shared
few details with American investigators, frustrating senior officials in
Washington. “They’re keeping us at a distance,” said one of the officials.

But investigators in Malaysia and the United States recently began receiving
additional data about the plane and anticipate receiving more over the
weekend, according to a senior American official. “It’s gotten better and
better every day,” the official said, referring to information from the
plane’s manufacturer, satellites and military radar. “It should provide
more clarity to the flight path. It’s not a given but it’s a hope.”
Because the plane stopped transmitting its position about 40 minutes after
takeoff, military radar recorded only an unidentified blip moving through
Malaysian airspace. Certain weather conditions, and even flocks of birds,
can occasionally cause radar blips that may be mistaken for aircraft, and
the Malaysian authorities say they are still studying the signals to
determine if they came from Flight 370.
But the person who examined the data said it leaves little doubt that the
airliner flew near or through the southern tip of Thailand, then back across
Peninsular Malaysia, near the city of Penang, and out over the sea again.
That’s in part because the data is based on signals recorded by two radar
stations, one at Butterworth air force base on the peninsula’s west coast,
near Penang, and the other at Kota Bharu, on the northeast coast. Two radars
tracking a contact can significantly increase the reliability of the
readings.
Still, Ravi Madavaram, an aerospace engineer at the consulting firm Frost &
Sullivan based in Kuala Lumpur, said the accuracy of ground-based radars
determining a plane’s altitude falls the farther away the plane is. When
Flight 370 lost contact with ground control, it was more than 100 miles from
Kota Bharu and 200 miles from Butterworth, distances that he said could
degrade accuracy. But the altitudes measured as the plane crossed the
peninsula would be more reliable, he said.
Military radar last recorded the aircraft flying at an altitude of 29,500
feet about 200 miles northwest of Penang and headed toward India’s Andaman
Islands.
Cengiz Turkoglu, a senior lecturer in aeronautical engineering at City
University London who specializes in aviation safety, said dramatic changes
in altitude can be the result of a deliberate act in the cockpit. “It is
extremely difficult for an aircraft to physically, however heavy it might be
, to free fall.”
An Asia-based pilot of a Boeing 777-200, who asked not to be identified
because he was not authorized to speak to reporters, said an ascent above
the plane’s service limit of 43,100 feet, along with a depressurized cabin,
could have rendered the passengers and crew unconscious, and could be a
deliberate maneuver by a pilot or hijacker.
American officials were initially concerned in the first few days after the
plane went missing that terrorists had brought it down. But as agents have
examined the flight manifest and investigated the two Iranian men who were
on the plane traveling with stolen passports, the agents have become
convinced that there is not a clear connection to terrorism.
As part of its investigative efforts, the F.B.I. interviewed family members
of the Iranian men and used computer programs to determine whether they had
ties to known terrorists. Those efforts showed no connections to terrorism,
leading the investigators to believe the men were smugglers.

Investigators considered but dismissed the possibility that hijackers landed
the plane somewhere for later use in a terrorist attack, according to a
senior American official briefed on the investigation.
The data, the official said, “leads them to believe that it either ran out
of fuel or crashed right before it ran out of fuel.”
It would take a substantially long runway to land a plane of that size, the
official said, adding that although the radius the plane could have flown
extends into territory in South Asia, “the idea it could cross into Indian
airspace and not get picked up made no sense.” | P******a
