A satellite
transmitter on the plane was active for about five hours, indicating the plane
was operational after its transponder shut down less than an hour after
takeoff, said three U.S.
government officials. The 777 can cruise at 500 miles (805 kilometers) an hour
or more, meaning it may have flown for as far as 2,500 miles beyond its last
point of contact if it was intact and had enough fuel.
The
information adds to the mystery surrounding the March 8 disappearance of the
Malaysian Airline System Bhd. plane carrying 239 people. With no evidence of a
mechanical failure or pilot error, U.S. investigators are treating the
disappearance as a case of air piracy, though it remains unclear by whom, one
person said.
Satellite
Signaling
“I can’t think
of a single example of a large airplane completely disappearing without
seemingly leaving a trace for this many days,” said Hans Weber, president of
Tecop International Inc., a San Diego-based consultant.
The
satellite communications came from an onboard monitoring system that, if fully
activated, can send data about how the plane’s equipment is working to Boeing,
according to the person familiar with the equipment.
While
Malaysian Air never subscribed, meaning the system didn’t gather detailed information
about the flight, it was in an idle position of sorts and periodically sent a
pulse to a satellite.
The data
doesn’t necessarily indicate the jet was flying the whole time. It may be
possible for the system to operate if the 777 was on the ground, the person
said. It probably can’t operate following a crash, especially on the water
where components would likely sink, the person said.
Naval
Search
Inmarsat
Plc (ISAT), the London-based satellite operator, picked up “routine, automated
signals” from Flight 370, according to a statement e-mailed by Jonathan
Sinnatt, a spokesman. He declined to elaborate.
Inmarsat
shared its information with SITA, the main carrier in that region for land- and
satellite-based message traffic between aircraft and ground personnel. SITA in
turn shared the data with Malaysian Airlines, he said.
Radar
signals sent from the ground continued to reflect back from Flight 370 after
its transponder went dead as the aircraft headed north from Malaysia toward Vietnam , said the people. After the
transponder shut off, making the 777 harder to follow on radar, the plane
turned left toward the west instead of continuing on its path.
South Korea
is readying planes to help search for the missing jet, Defense Ministry
spokesman Kim Min Seok says at a briefing today. Vietnamese aircraft will
continue searching in the area east of the airplane’s last known location in
the South China Sea, as other nations search in the west, Lai Xuan Thanh, head
of the country’s Civil Aviation Authority, said by phone today.
Indian Navy
The search
by India ’s navy covers
35,000 square kilometers (13,514 square miles) off the northern tip of Sumatra , Indonesia ’s
largest island. That is on the opposite side of Malaysia
from the plane’s intended path to Beijing from Kuala Lumpur .
Search Area
The search
area has a northern edge 270 nautical miles from Port Blair and a western edge
70 nautical miles from Campbell
Bay , said D.K. Sharma, an
Indian Navy spokesman.
U.S.
investigators have been studying a radar blip detected hundreds of miles west
of the plane’s intended route, in the area of the Malacca Strait, about 2:15
a.m. local time March 8. That was 45 minutes after contact was lost with the
jet flying to Beijing through the Gulf of Thailand .
The 777 had
enough fuel to fly the 2,700 miles (4,345 kilometers) to Beijing and reserves to fly to a diversion
airport.
The
aircraft’s transponder normally sends signals to ground radar stations making
it easier to follow and providing other information, such as its identity and
altitude. While it’s possible for the unit to malfunction or be accidentally
switched off, it is highly suspicious for the device to fail at the same time a
plane makes an abrupt change of course.
‘Truly
Agonizing’
Planes and
ships from a dozen countries scouring land and sea on both sides of Peninsular
Malaysia have yielded few answers on what caused Flight 370 to disappear.
The U.S.
National Geospatial-Intelligence Agency is supporting the Department of Defense
to find the missing aircraft, said spokesman Donald Kerr in an e-mailed
statement. The Defense Department is following up on all leads on the potential
path of the aircraft and assisting U.S. Pacific Command in its search for
debris fields.
“It’s
frustrating for everyone, but agonizing for the families of those passengers on
the flight,” White House Press Secretary Jay Carney said at a briefing in Washington yesterday.
“Our thoughts and prayers go out to them especially because this is truly
agonizing for them.”
The U.S.
Navy is moving the destroyer USS Kidd from the Gulf
of Thailand to the Strait
of Malacca to help in the search, Commander William Marks, a
spokesman for the Navy’s Seventh Fleet, said in an e-mail.
It also
will move a P-8A Poseidon aircraft into the area tomorrow to rotate with a P-3C
Orion craft that has been involved in the search, he said. The P-3C is still in
the Gulf of Thailand area, according to Pool, the
Pentagon spokesman.
Boeing said
it already has investigators on site to assist the U.S. National Transportation
Safety Board. These teams would probably include 777 structures experts who can
quickly identify crucial aircraft components, said John Purvis, a retired
accident investigator who headed Boeing’s investigations unit for much of the
1980s and 1990s.
