Malaysia Airlines Flight 370: A pilot suicide mission?
Malaysia Airlines Flight 370: The missing aircraft
is now prompting theories that the aircraft was hijacked or the crew chose to
change course. Could Malaysia Airlines Flight 370 be similar to SilkAir Flight
185, a pilot suicide tragedy in 1987?
On Dec. 19, 1987, SilkAir
Flight 185 took off from Indonesia, bound for Singapore. There were 97
passengers and seven crew on board as the flight lifted off at 3:37 p.m. local
time.
Thirty-five minutes later, the aircraft mysteriously and suddenly
dove vertically into Musi River in Sumatra. All on board perished.
The
Indonesian government investigation said the cause of the crash was
"inconclusive."
But the US National Transportation Safety Board, which
worked jointly with the Indonesian team, concluded that the pilot committed
suicide. In a letter to the Indonesian safety committee, the NTSB
wrote:
The examination of all of the factual evidence is consistent with
the conclusions that: 1) no airplane-related mechanical malfunctions or failures
caused or contributed to the accident, and 2) the accident can be explained by
intentional pilot action. Specifically, a) the accident airplane's flight
profile is consistent with sustained manual nose-down flight control inputs; b)
the evidence suggests that the cockpit voice recorder (CVR) was intentionally
disconnected; c) recovery of the airplane was possible but not attempted; and d)
it is more likely that the nose-down flight control inputs were made by the
captain than by the first officer.
There are a number of parallels that
are now being drawn in online aviation forums between the Malaysia Airlines
Flight 370 and the SilkAir 185 tragedy.
The only new information in the
last 24 hours is that military radar tracks the aircraft making an abrupt change
of course and flying for an hour and 10 minutes west over the Malaysia peninsula
and into the Strait of Malacca. At that last known position, presumably when the
military radar lost contact, the aircraft was at 29,500 feet, according to
Malaysia's Air Force chief Rodzali Daud.
Why no radio communication? Why
not transponder signal? Why no contact at all with the ground as the plane
continued at just a few thousand feet below cruising altitude for more than an
hour?
Most aviation professionals suggest that a flight crew member would
know how to turn off or disable radio, transponder, and the Aircraft
Communication Addressing and Reporting System (ACARS), the on-board systems
monitoring equipment that transmits information back to the
airline.
"Hijacking or a pilot going rogue would explain the
transponder and ACARS not transmitting. If this is what actually happened, I
fear the CVR and FDR would have been turned off also, thus giving the
authorities very little chance of knowing what actually happened," writes
"garpd," an aviation graphics designer in the UK on Airliners.net.
The
Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR) could be turned off
by tripping a circuit breaker. In the SilkAir investigation, the pilot was
suspected of manually tripping the circuit breaker on the CVR and then, the FDR,
thus eliminating any recording of events during the final minutes of that
flight.
Malaysian authorities say they are now doing deeper background
checks on passengers and crew.
"Maybe somebody on the flight has bought a
huge sum of insurance, who wants family to gain from it or somebody who has owed
somebody so much money, you know, we are looking at all possibilities,"
Malaysian police chief Khalid Abu Bakar told a news conference Monday. "We are
looking very closely at the video footage taken at the KLIA (Kuala Lumpur
International Airport), we are studying the behavioral pattern of all the
passengers."
Again, there's the echo of SilkAir Flight 185.
Capt.
Tsu Way Ming, the pilot of SilkAir 185 reportedly had $1 million in security
trading losses 10 days before his last flight. He bought a life insurance policy
the week before his last flight, according to Macarthur Job, who wrote about the
incident for Flight Safety Australia in 2008.
But if the Malaysia
Airlines flight was a planned suicide, why did whomever was at the controls turn
the aircraft west and fly for at least another hour?
If it was a
hijacking, then based on the original flight plan and fuel, the search area
could be much larger - as large as 3,000 miles in diameter - or all the way to
India or deep into China.
In the unusually long absence of information
about the location of Malaysia Airlines Flight 370, speculation continues. And
the search by authorities is turning inward - toward examining more closely the
crew and passengers - for clues to the cause of the flight's disappearance.
