How did MH370 crash and when did Malaysia Airlines MH370 crash

The cause is still under investigation, and the research process is as follows:

Malaysian officials have announced the basic research and judgment process from relevant British agencies to determine that MH370 fell into the southern Indian Ocean. Experts from the British Aviation Accident Investigation Agency (AAIB) and the International Maritime Satellite Organisation (Inmarsat) and the Malaysian side will explain the relevant content to the families in detail.

Authorities determined that the plane was heading for the southern Indian Ocean by detecting pulse frequency shifts in the "hand shake" signal between the aircraft and the satellite, and between the satellite and the ground receiving station. This new method uses the "Doppler contribution", a theory derived from the Austrian physicist Doppler. In a nutshell, the phenomenon of a change in frequency is felt by the observer due to the relative motion between the source of the wave emitting the sound or electronic signal and the observer (receiver).

This change is called an "offset" and can also be measured in the unit of "Hz" by the instrument.

In the MH370 case, the relative position between the communication satellite and the earth is fixed, and the relative position of the MH370 aircraft will change relative to the satellite when it moves north or south over the Strait of Malacca. When the aircraft transmits the "handshake signal" at different positions, and when it is transmitted to the ground receiving station by satellite, a small difference between the signal pulse intensity and the preset strength will occur, and the speed and course of the aircraft can be judged by comparing the simulated scenes.

Inmarsat has announced that after MH370 turned off the Aviation Response System (ACARS) and the turnaround, they received at least six times that the aircraft had "shaken hands" with the satellite via the satellite data link, basically at one-hour intervals. A vice president of the agency said that this was because the airlines did not purchase information services that continuously track the trajectory of aircraft. According to Malaysia, the agency and the AAIB also conducted simulation scenario experiments based on data from six Boeing 777 aircraft, and finally determined that the burst frequency offset received by the satellite receiving station was different when the MH370 flew in different directions.

Relevant materials show that it is through the satellite signal ground receiving station in Australia that the heading and speed of the aircraft are offset by pulse frequency. The graphs released by the Malaysian side show that the curves derived from this analysis show that the data on the frequency shift of the signal pulse is highly consistent with the data on the flight to the southern Indian Ocean in the simulated scenario. If the plane is flying to the northern route, the offset calculated at the last signal "handshake" is about 50 Hz lower.

Malaysian officials believe that the last time the plane tried to "shake hands" with the satellite was at 0:11 UTC (8:11 Beijing time), and no relevant signals were received after 0:15. With no land to land, the Malaysian side believes that the plane has crashed into the southern Indian Ocean.

In terms of being issued, because of being issued, because of being issued.

Malaysia Airlines MH370 was March 8, 2014.

On March 8, 00:42, flight took off from Kuala Lumpur International Airport in Malaysia and was scheduled to land in Beijing at 06:30.

At 01:20, the flight lost contact with the Ho Chi Minh area at the junction between Malaysia and Vietnam, and did not receive a distress signal from the missing aircraft.

2. Malaysia Airlines MH370 disappeared at 06°55 15 N, 103°34 43 E longitude, passengers from 14 countries or regions, and a total of 239 passengers - including 227 passengers (2 infants) and 12 crew members.

There is no big change, there is no big change in the machine, machine.

At 2:40 a.m. on March 8, 2014, Malaysia Airlines flight MH370, a Boeing 777-200 with 239 passengers on board, was scheduled to fly from Kuala Lumpur to Beijing.

In the early hours of March 8, 2014, radar coverage of the border between Malaysia and Vietnam lost contact with air traffic control.

It's just lost contact at the moment! The wreckage has not been found at all, it is still a mystery, M H 370

In fact, the biggest possibility at present is a crash, but there may be several reasons why no early warning distress signal was issued:

According to many scientific arguments, there is no possibility that MH370 was hijacked, but there has been no final result to determine, but there is no doubt that no party has come out to clarify that it was not shot down by a missile, because the altitude of the plane was not very high shortly after takeoff, and it is very likely that it was shot down, and there was no time to report the actual situation of the plane, but have you considered disappearing without so many debris?

So let's wait patiently for the final news, any remarks are just speculation as usual, I hope that there is a special phenomenon similar to a space-time tunnel or wormhole, maybe 20 years from now, this plane will still appear on this route.

It can't be, because there are so many satellites in the sky around the world, and if such an accident happens, there is no reason why satellites can't detect it.

I wondered if it would be a supernatural phenomenon, as I said in the previous Exploration and Discovery, there was a time in the 70s of the 20th century when the plane disappeared, but ten years later, the plane landed, and the passengers did not change after landing, and I thought it was a few hours later.

I don't think any terrorist group has been able to make a plane disappear for as long as this tech zone, and if a terrorist group hijacks it, it must be more than just the oil on the news.

The latest movement of MH370, suspected of being shot down by a missile? Western detectives point the finger at the country.

The ultimate conjecture and event review.

1.Q: Why do hijackers keep flying?

A: Because the hijackers have been waiting for a reply from Ma**.

2.Q: Why did Malaysia announce that the plane was missing five hours after it went missing?

Answer: Because Ma ** was bargaining with the hijackers in Xuchang, the plane did not lose contact during the past five hours, the communication between Ma ** and the hijackers had been smooth, and Ma ** also hoped to persuade the hijackers to give up the hijacking unconditionally, so he could not release information. In fact, the plane has been cruising back and forth in the vicinity of the Malaysian Bird, waiting for a reply from Ma **.

Only in the end did it disappear on the radar to the northwest. The hijackers' political demands are mainly domestic to Malaysia, so there is no need to fly to another country. Moreover, the hijackers hoped that they would agree to the conditions and that they would return alive, and they would not fly to the Indian Ocean or Kazakhstan, so there would be no way out and there would be no need.

But in the end of the flight ran out of fuel.

3.Q: What was Malaysia** doing when it confirmed that the jet fuel was exhausted?

Answer: We quickly set a strategy to conceal the truth and announced the information about the loss of contact with the plane. Then they misled the international community and created the false impression that they could not find the plane.

4.Q: Why does Malaysia lie?

A: Because if the political demands of the hijackers are known to the public, it will cause political **, and if the international community knows that Malaysia** refuses to allow the hijackers to have the plane destroyed, Malaysia will be discredited.

5.Q: What role did the United States and Boeing play in the incident.

The United States has known the truth for a long time. Ma ** tried to disguise the incident as an ordinary aviation accident or a mystery who could never find the wreckage of the plane, and then compensated the family. But Boeing couldn't stand it, and they didn't want to bear the black pot of the plane's quality problems, so Boeing and the United States ** announced ironclad evidence that the plane flew for another 5 hours after losing contact.

In the face of ironclad evidence, Ma ** was forced to admit that it was a hijacking, not a technical failure of the aircraft. In fact, the United States has long known the whole truth, including the plane that flew there at the end, but the United States only releases what is beneficial to itself, so as to blackmail Ma ** in order to obtain huge political benefits.

Maybe it's because there's not enough fuel.
