Where is Flight 370?
10 Big Questions Source: CNN.com
Every day brings new details and new questions surrounding the disappearance of Malaysia
Airlines Flight 370, a Boeing 777 with 239 people aboard that went missing on March 8 en route from
Kuala Lumpur to Beijing.
Here are 10 questions surrounding what we know and what we don’t know:
1. What do we know about the pilots?
The pilot, Capt. Zaharie Ahmad Shah, 53, has 18,365 flying hours. He joined the airline in 1981.
For a veteran 777 pilot with Shah’s background, 18,000-plus total career hours in the air is normal.
Shah built a flight simulator in his home. It’s somewhat common among the worldwide
community of aviation enthusiasts to use online flight simulator programs to replicate various situations.
Simulators allow users to virtually experience scenarios in various aircraft.
Programs can simulate flight routes, landings and takeoffs from actual airports, but pilots say they
cannot replace the experience gained from real flying.
Shah is married and has three children, the youngest of whom is in her 20s and lives with her
parents. He and his wife have one grandchild.
First Officer Fariq Ab Hamid, 27, joined Malaysia Airlines in 2007. He has 2,763 flying hours
and was transitioning from flight simulator training to the Boeing 777-200ER.
The amount of flight time Hamid has could be a bit low for a 777 pilot flying for an American
airline, experts said. But the system of pilot advancement is often faster among airlines in smaller nations.
Some airlines in these countries offer cadet programs that find talented and promising young pilot
candidates and offer them intensive, specialized training, experts say.
Hamid lives with his parents and some of his four siblings, according to a neighbor. A source
close to the investigation told CNN that Malaysian police searched Shah’s and Hamid’s homes Saturday.
2. What do we know about communications to and from the plane?
Key clues about the plane have come from developments surrounding data and voice
communications. The plane is equipped with a standard voice communication radio and two other kinds
of communication technology: transponders and the Aircraft Communications Addressing and Reporting
System, known by the acronym ACARS.
The last known voice communication from the 777’s cockpit was these words: “All right, good
We don’t know whose voice spoke the words, but they were uttered as the plane neared
Vietnamese air traffic control airspace at about the same time the transponder was shut off, according to
Malaysian Prime Minister Najib Razak.
Because of the vital information a transponder provides, it would be highly unlikely for a pilot to
shut it off. Transponders are considered reliable, but they occasionally fail, which is why there is a backup
One way to hide a plane’s flight information from air traffic controllers would be to turn off the
transponder. Experts give conflicting opinions about what the transponder shutoff could mean: One
theory points to someone — perhaps a hijacker — wanting to hide the plane before changing course;
another theory is the transponder could have stopped transmitting because of a catastrophic power failure.
A series of “handshakes” — or electronic connections — from the plane’s ACARS was transmitted
to satellites for four to five hours after the transponder stopped sending signals, a senior U.S. official told
routine messages to the airline, such as when the aircraft lifts off or lands and how much fuel it may have,
he said. It can also be used to communicate text messages, for instance when the aircraft encounters
turbulence. ACARS typically beams down engine parameters, temperatures, the amount of fuel burned
and any maintenance discrepancies.
According to Malaysia Airlines, all of its aircraft are equipped with ACARS. “Nevertheless, there
were no distress calls, and no information was relayed,” the airline said.
The aircraft’s ACARS was sending pings more than five hours after the transponder last emitted a
signal, an aviation industry source told CNN on Friday.
These pings don’t provide information about speed or altitude, but they do indicate the plane was intact
for that long, since an aircraft has to be powered and have structural integrity for the ACARS to operate,
the source said.
The pings were detected by satellites and were used, with radar and other data, to calculate where
the plane might have traveled. A U.S. official, who spoke to reporters on condition of anonymity, said a
satellite recorded electronic “handshakes” with the 777 that were later analyzed.
The information gleaned from this analysis — which the U.S. official described as
“unprecedented” — supports the conclusion that the aircraft turned toward the west, away from the Gulf of
Thailand and toward the Indian Ocean. Referring to the five- to six-hour range in which the plane may
have flown after its transponder cut off, the same official said, “We believe we have the time of the loss
of the airplane within an hour.”
But on Saturday, Malaysian Prime Minister Najib said that “based on new satellite
communication, we can say with a high degree of certainty that … ACARS was disabled just before the
aircraft reached the east coast of peninsular Malaysia.”
3. Where could the plane be? What could have happened to it?
The evidence is growing that the plane flew for hours after losing contact with air traffic control.
Malaysia’s aviation authorities, with agreement from U.S. and British government experts,
concluded the plane’s last communication with the satellite was in one of two possible corridors. One
stretches from the border of Kazakhstan and Turkmenistan to northern Thailand; the other from Indonesia
to the southern Indian Ocean.
The latest data and calculations provided by Malaysian officials show an arc of places the aircraft
could have traveled. Because the northern reaches of the arc include some tightly guarded airspace over
India, Pakistan and U.S. installations in Afghanistan, U.S. authorities believe it more likely the aircraft
crashed south of India into waters outside the reach of radar, one U.S. official said.
Had it flown farther north, it would likely have been detected by radar, the official said.
A classified analysis of electronic and satellite data suggests Flight 370 likely crashed either in
the Bay of Bengal or elsewhere in the Indian Ocean, CNN learned Friday.
The analysis, conducted by the United States and Malaysian governments, used radar data and
satellite pings to calculate that the plane diverted to the west, across the Malay Peninsula, and then either
flew in a northwest direction toward the Bay of Bengal or southwest into another part of the Indian
Ocean. Malaysian military radar registered dramatic changes for Flight 370 in altitude and it cut an erratic
path across Malaysia in what are some of the last known readings of its location, according to a senior
The same official, who is familiar with analysis of the data and declined to be identified because
of the sensitive nature of the information, cautioned that this assessment is not definitive. The readings
may not be wholly reliable because of the distance of the plane from the radars that detected it, the official
4. Couldn’t a pilot just ‘fly under the radar’?
Theoretically, yes. As a tool intended to keep track of what’s going on in the sky, radar doesn’t
acquire data all the way to the ground.
Military pilots are trained to take advantage of this when they need to go undetected. But their
aircraft are also equipped with terrain-evading radar and other features intended to help fighter and helicopter pilots hug the ground, said aviation consultant Keith Wolzinger of the Spectrum Group.
Understandably, Boeing doesn’t offer those features on its commercial airliners.
“Airline pilots are not trained for radar avoidance,” said Wolzinger, himself a former 777 pilot.
“We like to be on radar.”
Also, unlike military craft, civilian airliners don’t have gear to detect when they’ve been spotted
on radar. So any efforts to fly undetected would be rudimentary.
5. Could the plane have landed somewhere?
One theory U.S. officials are considering, according to a Wall Street Journal report, is that
someone might have taken the plane to be used for some other purpose later. So it’s theoretically possible
that the plane could have landed at a remote, hidden airstrip.
There are some large holes in that theory. The 777 is a big plane. It requires, at minimum, nearly
a mile to land. And, says CNN aviation correspondent Richard Quest, there’s the matter of getting it
someplace without setting off alarm bells.
“You can’t just fly a 777 and not have a radar trace,” he said. One senior U.S. official, citing
information Malaysia has shared with the United States, told CNN that “there is probably a significant
likelihood” that the aircraft is on the floor of the Indian Ocean.
6. How likely is hijacking or terrorism in this situation?
The CIA and FBI aren’t ruling it out, but authorities aren’t ruling out much at this point. It’s highly
suspicious that the plane seems to have turned around. Those suspicions are further fueled by the loss of
communications with the plane, considering the aircraft had “redundant electrical systems” that would
have had to be disabled.
Robert Francis, former vice chairman of the U.S. National Transportation Safety Board, said his
first thought upon hearing the circumstances of the flight’s mysterious disappearance was that it blew up,
but even an explosion would not be proof of terrorism.
The two men who used stolen passports to board the plane were identified by Interpol as Iranians
Pouri Nourmohammadi, 18, and Delavar Seyed Mohammad Reza, 29. Malaysian investigators say neither
of them has any apparent connection to terrorist organizations.
Stolen passports don’t necessarily indicate terrorism. In fact, passengers flew without having their
travel documents checked against Interpol’s lost-and-stolen passport database more than a billion times in
2013, according to the international police organization. Among the reasons someone might use a stolen
passport: to emigrate to another country, to export goods without paying taxes or to smuggle stolen
goods, people, drugs or weapons.
7. Could mechanical failure explain it?
It’s one of the possibilities, but less so since Najib said on Saturday that the plane’s movements
“are consistent with deliberate action by someone on the plane.”
The absence of a debris field could suggest that the pilot might have made an emergency landing on water
and the plane then sank intact, but there was no distress signal.
However, aviation consultant Kit Darby has said there might have been a power failure, and
during the hour when he had backup power, the pilot was attempting to return to “the airports and a
region he knows.” There’s also the possibility that the tail or a wing tore from the fuselage. This particular
Boeing had suffered a clipped wingtip in the past, but Boeing repaired it.
Another possibility is that a window or door failed, which would cause the temperature inside the
plane to drop to 60 degrees below zero, creating a freezing fog and giving crew members only seconds to
don oxygen masks before becoming disoriented and then incapacitated.
8. What other theories and speculation have been offered?
Lithium batteries: Investigators are looking into the possibility that lithium batteries, which
have been blamed in previous crashes, played a role in the disappearance, according to U.S. officials
briefed on intelligence and law-enforcement developments. The officials spoke on condition of
anonymity because they were not authorized to speak to the media. If lithium batteries were being carried in the cargo hold, they could have causes a crash-inducing
fire. But that would not explain other anomalies, such as why the plane appears to have turned west. A
pilot’s likely first instinct if lithium batteries were smoldering would have been to turn around and return
to the airport of origin — not to fly an additional five hours, said Arthur Rosenberg, an aviation expert
who is a pilot, engineer and partner in the New York-based law firm Soberman & Rosenberg.
Meteor: A meteor was reported in the area around the time Flight 370 took off, but this seems to
be atop a list of strange theories popping up in the absence of empirical data explaining the plane’s
disappearance. Given what little is known about the flight path, and the astronomical odds against such an
event, a meteor strike seems like an ultralong-shot explanation.
9. What about reports that passengers’ cell phones continued operating after the flight’s
When phones are disabled or turned off — which would presumably happen after a plane crash —
calls to those cell phones go directly to voice mail. Friends and loved ones of the missing passengers,
however, reported ringing when they called. Technology industry analyst Jeff Kagan says a call would
connect first to a network before trying to find the end user, and the ringing sound callers hear masks the
silence they would otherwise hear while waiting for the connection to be made.
“If it doesn’t find the phone after a few minutes, after a few rings, then typically, it disconnects,
and that’s what’s happening,” he said.
10. Is this the first time a plane has vanished?
No. In 2009, Air France Flight 447 crashed in the South Atlantic between Rio de Janeiro and
Paris during turbulent weather conditions. It took four searches and almost two years before the bulk of
the wreckage and majority of bodies were recovered. The voice and data recorders weren’t found on the
ocean floor until May 2011.
Wow, I get losing cars and boats, but how in the world do you lose a plane. If I were on that plane, and I knew what was going on, I would be amazed that nobody could find one of the most biggest things that transports people from place to place. I have multiple ideas on who took the plane and where It might have gone. I think that when the death of osoma bin laden died on May 2nd 2011 in Pakistan. The al Qaeda must have been very upset. So they must have planned this out for a while, and they finally took another plane. If you do not think that this event is possible. People didn’t think 9-11 was possible. Now I am going to tell you were I think the plane has gone. Being honest, I think that the plane could still be in the sky. And they are trying terrorist are trying to pick another target. That is all I have to say, and that is what I think about the missing plane.
