US Officials: Missing Malaysia Airlines Plane’s Turns Suggest Control of Aircraft
            
    
            
        
Newly revealed information suggests a missing 
Malaysia Airlines
 jetliner made a turn up the Strait of Malacca subsequent to a 
previously reported turn to the west that occurred around the time air 
traffic controllers lost contact with the plane, a senior U.S. 
government official who has been briefed on the investigation told ABC 
News.
The turns are indicative of someone at the controls of the plane, the 
official suggested -- an assessment that other experts seemed to agree 
with.
"That indicates that somebody may be on the controls," said Tom Haueter,
 a former director of the National Transportation Safety Board's Office 
of Aviation safety. "Slight turns I can see, but if somebody is making a
 major heading change, that would appear to be an intentional input to 
the controls."
Mystery Surrounds Missing Malaysia Airlines Flight
 
 
Added Stephan Ganyard, an ABC News aviation consultant, "We are seeing 
what we call heading changes, where the aircraft changes its nose 
position and moves around the sky.  This would confirm that we are 
seeing an airplane that's being controlled by pilots or somebody in that
 aircraft."
The search for the missing jetliner is focusing on two widely separated 
quadrants, one in the Malacca Straits off the west coast of Malaysia and
 the other hundreds of miles away in the northern Bay of Bengal, a U.S. 
official said today.
The focus on those areas is based on sharing of data by Malaysia and the
 U.S. that has led to determinations that there is a higher probability 
that the jetliner took a path in either of those directions, the 
official said.
The first official added that the searches in those quadrants will begin taking place over the next 24 hours.
Those quadrants were settled on today after a satellite communications 
company said that the missing plane contacted its network on the day it 
disappeared in what could turn out to be a big break in the effort to 
locate the jetliner or determine where it went. It was the latest 
indication that the plane flew far from its designated flight path that 
was intended to take its 239 passengers to Beijing.
“The satellite is saying it’s a north arc and a south arc -- those would
 be the directions it would have gone in based upon the data, based on 
the pings,” according to a second U.S. source.
The pings evidently came from technology inside Boeing aircraft that 
transmits a signal to a satellite that even pilots may not know about, 
ABC News has learned. This system establishes what is described as an 
electronic “handshake” between the airplane and the satellite.
However, this signal is crude when it comes to location data, so 
investigators will still be faced with a significant search.   The pings
 occur every hour and ABC News has been told there were four or five of 
the transmissions. Searchers will use the last transmission to project 
out in their search.
Inmarsat, a British company, said today, "Routine, automated signals 
were registered on the Inmarsat network from Malaysia Airlines flight 
MH370 during its flight from Kuala Lumpur."
It said the information was shared with SITA, a company that specializes
 in air transport communications. SITA shared with details with Malaysia
 Airlines, Inmarsat said.
Inmarsat on its website said its satellite system "facilitates the 
automatic reporting of an aircraft’s real-time position, including 
altitude, speed and heading, via satellite to air traffic control 
centres, helping controllers know where an aircraft is at all times."
If those "pings" sent by the Malaysia Airlines jet to the satellite 
indicate location or flying direction, it could help solve the mystery 
that began a week ago when the jet disappeared from radar.
ABC News had previously reported that the missing plane continued to 
"ping" a satellite after two of its communications system, including its
 transponder, had shut down.
Inmarsat's statement came hours after investigators said they could not 
rule out hijacking and are looking at whether one of the plane's pilots 
or crew could have been involved.
Malaysia's Transport Minister Hishammuddin Hussein made clear that 
investigators do not know what happened to the jetliner despite a week 
of intense searching.
U.S. officials who have been briefed on the investigation have said two 
of the plane's communications systems were shut down separately and it 
appeared to have been done manually.
“There are four or five possibilities which we are exploring," 
Hishammuddin told a news conference today. "It could have been done 
intentionally. It could be done under duress. It could have been done 
because of an explosion. That’s why I don’t want to go into the realm of
 speculation. We are looking at the all the possibilities.”
When asked whether investigators were looking at whether one of the 
plane's two pilots or cabin crew could have involved in whatever 
happened to the plane, he replied. “We are looking at that possibility.”
“The investigation into the pilots is ongoing,” he said in response to 
another question, but said they have not yet searched their homes.
Malaysia Airlines CEO Ahmad Jauhari Yahya added to the speculation that 
the plane's disappearance was the result of a plot rather than a 
catastrophic failure of the airplane's systems. “We cannot confirm 
whether there is no hijacking. Like I said from the start, and I’ve been
 very consistent, we are looking at all possibilities,” Yahya said.
A senior U.S. military official told ABC News that they had not ruled 
out that the plane was flown to a secret site so it could be used at a 
later date.
"I am keenly interested in resolving this mystery so we can discard the 
possibility, however remote, that the airplane can be used for nefarious
 purposes against us in the future," the official said.  The official 
added that "all our intelligence assets" are being used to try to figure
 this out.
The plane vanished early Saturday about an hour after taking off from 
Kuala Lumpur and heading for Beijing. It disappeared from radar at 1:30 
a.m. local time. After searching intently east of Malaysia in the Gulf 
of Thailand and the South China Sea, much of the attention has shifted 
hundreds of miles west in the Strait of Malacca and the Indian Ocean. 
Officials believe it may have flown west because Malaysian military 
radar picked up a signal after the jetliner disappeared and they believe
 it may have been flight MH370.
“I will be the happiest person if we can confirm that [the military 
radar blip] is MH 370 because then we could move all our assets to the 
Strait of Malacca. But at this time we cannot do that,” Hishammuddin 
said today.
Investigators are trying to retrieve data from the satellites that had 
been pinged by the missing airliner in the hopes that those contacts 
might aid in plotting the plane's final position.
Vietnamese officials added some detail to the plane's mystery today by 
telling ABC News that when flight MH370 left Malaysian airspace and 
failed to make contact with Vietnamese air traffic controllers, the 
Vietnamese asked another plane in the area that was heading to Japan to 
contact MH370.
The Japan-bound plane reported back to the Vietnamese controllers that 
when it reached MH370 only a “buzz signal” came back, but no voices. And
 then the signal went dead. The Vietnamese Ministry of Foreign Affairs 
did not say what time that contact was made.
The destroyer USS Kidd arrived in the northwestern section of the Strait
 of Malacca today to help search that vast expanse of sea.
