Author - William Langewiesche, a professional and veteran aviator in the field of aviation, believes that land officials know more about the cause of the incident than they dare to say. out.
Below, the newspaper would like to introduce Mr. Langewiesche’s article on the incident MH370, one of the most mysterious missing plane cases in the history of the world:
Period I: Missing mystery
At 0:42 minutes on a bright, peaceful moon on March 8, 2014, the Boeing 777-200 of Malaysia Airlines, bearing the number MH370 departs from Kuala Lumpur to depart for Beijing, China.
The plane quickly reached an altitude of nearly 10,700m indicated for the journey. The main driver was vice-captain Fariq Hamid, 27 years old.
This is the last training flight, which is expected to help him get a full vocational qualification soon.
Fariq’s coach is also the captain of the flight - Zaharie Ahmad Shah, 53, one of the highest-ranking captain at Malaysia Airlines. Mr. Zaharie is married, has 3 children and owns two houses. In his first home, he installed a complex flight simulation system.
Mr. Zaharie flies regularly and also posts his interests on online forums. In the cockpit, Fariq showed respect while Mr. Zaharie was not overbearing.
On the aircraft cabin MH370 has 10 seats, all are Malaysian. They serve 227 passengers, including 5 children. Most of these passengers are Chinese. The rest include 38 Malaysian nationals and passengers from Indonesia, Australia, India, France, the US, Iran, Ukraine, Canada, New Zealand, the Netherlands and Russia.
At the cockpit that night, while vice commander Fariq flew the plane, Captain Zaharie managed the radio. This arrangement is standard, but Mr. Zaharie’s way of communicating is a bit unusual. At 1:01 am, he reported that the plane was stalling at an altitude of nearly 10,700 meters, an unnecessary report in airspace with surveillance radar, where pilots often only reported leaving a height, not reaching. to some height.

At 1h08, the plane crossed the Malaysian coast and flew over the East Sea in the direction of Vietnam. Mr. Zaharie once again reported that the altitude of the aircraft was nearly 10,700 meters. 11 minutes later, when the aircraft approached the starting point of Vietnam’s air traffic jurisdiction, air traffic controllers at the Kuala Lumpur Center informed via radio: "Malaysia 370, contact Ho Chi Minh City. Minh 120.9. Good night ". Captain Zararie replied: "Good night. Malaysia 370".
Zararie did not re-read the frequency as he should, but it still seemed normal anyway. This is the last time the world hears the message from MH370. The crew never registered to the TP air traffic control station. HCM and also did not respond to any efforts to call them later.
The main radar relies on simple "ping" sounds from objects in the sky. Air traffic control systems use secondary radar, which depends on the signal of the transmitter relayed by the aircraft and contains more information (such as aircraft identification and height) compared to radar. main supply.
5 seconds after MH370 flew into Vietnam airspace, the symbol representing the air transponder no longer appears on the screen of Malaysia air traffic control agency. And 37 seconds later, the entire plane disappeared from the secondary radar. It was at 1:21 on March 8, 39 minutes after the plane took off.
Kuala Lumpur air traffic controllers are busy handling other flights on the screen, so they simply don’t pay attention. When he finally realized the change, he assumed that the plane was under the control of the TP station. HCM.
Meanwhile, Vietnamese air traffic controllers saw MH370 fly into space and then disappeared from the radar. They tried to contact the aircraft many times but failed to get results. Vietnamese air traffic controllers called to inform the incident to Kuala Lumpur.
Malaysia’s aerospace rescue coordination center should have reported the incident within an hour of missing aircraft. But until 2:30, that has not been done yet. More than 4 hours passed, at 6:30 am, authorities finally began an emergency response. At that time, the aircraft should have landed in Beijing.
The search MH370 was initially concentrated in the South China Sea, between Malaysia and Vietnam. It is an international effort that brings together 34 ships and 28 aircraft from 7 different countries.
Within a few days, major radar records were collected from air traffic control computers as well as partly authenticated by Malaysia’s secret air data revealed, as soon as MH370 disappeared from the secondary radar, the machine flew to the southwest, flew back through the Malay Peninsula and moved around Penang Island. From there, the aircraft headed northwest to the Malacca Strait and crossed the Andaman Sea, where it crossed the radar’s visible range and entered the obscured area.
That period took place over an hour, hinting that this was not a typical hijacking. Everything is not the same as a crime or a pilot scenario like the one people have met before. From the beginning, MH370 led investigators in ways never explored.

The mystery surrounding MH370 is the focus of investigation and is also the source of speculation, the hypothesis sometimes shocks public opinion. Losses devastated the victim families on four continents. No one thinks a sophisticated machine, equipped with modern tools and redundant communication devices, can disappear without a trace.
In this day and age, it is very difficult to permanently erase an e-mail .. and living out of the network is almost impossible even if we deliberately do it. The design of a Boeing 777 allows access to electricity at all times.
Despite all that, MH370 was actually missing and after more than five years of searching, no one knew exactly the fate of this passenger plane. However, many details of the disappearance of MH370 are gradually elucidated and reconstruction of what happened on the fateful night is possible even though investigators have not found two black boxes of aircraft (including cockpit recording device and flight data recording device).
Unusual traces
Despite Malaysian officials’ rejection and the Air Force’s concealment, the truth about MH370’s strange path quickly revealed. As it turned out, the aircraft continued to connect with a static Indian Ocean satellite operated by Inmarsat, a London commercial supplier, for six hours after the aircraft disappeared from the secondary radar. This means, the plane does not suddenly suffer from a slump.

During those 6 hours, MH370 was still allowed to move up high, at great speed. Inmarsat connections, with some of them often referred to as "handshakes," are electric light spots that flash on the radar screen. These are regular connections that show the best communication whispers, because of the intentional content of the system such as the passenger entertainment system, text messages in the cockpit or automatic maintenance reports. has been separated or turned off.
In total, there are 7 connections of MH370 with Inmarsat satellite: 2 automatic starting connections from the aircraft and 5 other connections are automatically generated from Inmarsat ground station. There are also 2 satellite phone calls. They are not answered but provide additional data.
Accompanying most of the above connections are the two numbers that Inmarsat just started to find recently. The first and main values are rather than the boom time offset, which Langewiesche calls "distance value". This is a measure of the time it takes to get to and from the plane, so the distance from the plane to the satellite. It does not indicate a specific position but is all equivalent positions, a nearly circular set of possibilities.
Considering the flight range limits of MH370, those round circles can be reduced to arc shapes. The most important arc is the seventh and final arc, as the final "handshake" is established while adhering to complex ways, depleting fuel and damaging the main engine.
The seventh arc stretches from Central Asia to the north to the South Pole neighborhood to the south. MH370 surpassed this arc at 8h19 on March 8, 2014, in Kuala Lumpur time. The calculation results of the flight capabilities of MH370 set the plane’s intersection with the seventh arc (the end of MH370) in Kazakhstan if the plane turns north or south of the Indian Ocean if it turns to South.
Technical analysis shows that it is almost certain that the ill-fated plane has moved south. This is derived from the second detection value of Inmarsat - explosion frequency offset. Langewiesche expert calls this number simply "Doppler numerical value" because it mainly consists of a measurement of Doppler radio frequency switching associated with high-speed motion related to satellite position.
This is also the natural part of satellite communications for aircraft in flight.
Aerial systems must predict and compensate for Doppler switching so that satellite communication is normal. However, the offset process is often imperfect because the satellites, especially when over many years of operation, no longer transmit the main signal in the way the plane has been programmed to receive. Their trajectories may tilt slightly. They are also influenced by temperature. Imperfections always leave traces.
Although the Doppler shift records had never been used before to locate the aircraft, Inmarsat’s technicians in London were able to recognize a significant distortion. refers to MH370 turning south at 2:40. The turning point is slightly slanted to the north and west of Sumatra, Indonesia’s northernmost island. It is assumed that MH370 then flies straight and very long toward Antarctica, the area beyond its range.
After 6 hours, Doppler data showed a 5-fold faster drop in normal speed. Within 1-2 minutes of crossing the seventh arc, the plane plunged into the ocean, possibly breaking parts before it collided. From electronic evidence, experts say this is not a controlled water landing effort. The plane has certainly crumbled into millions of pieces immediately.
However, no one knows where the plane fell and why it happened. Moreover, no one has in hand any of the smallest physical evidence to confirm that the above satellite interpretations are correct.
