In which country did mh370 disappear from air traffic control radar?
On 1: 2 1 in the morning, when the flight arrived at the junction of Malaysia and Vietnam (destination Igari), due to unknown reasons, the crew suddenly turned off all communication equipment including the answering machine, resulting in the flight losing contact with the flight information region of Ho Chi Minh City. At that time, the weather was fine and the flight did not send out any distress signal. Afterwards, the civil radar could not track the flight, but the Malaysian military captured its radar reflection.
At 1: 30 in the morning, a Boeing 777 flying to Narita Airport in Japan contacted MH370 at the request of the Vietnamese air traffic control unit, but the radio signal was disturbed and could not be heard clearly. According to the captain of the plane, this was the last time they heard the sound of flight MH370, and then they lost contact. At the same time, the flight crew did not hear the distress signal of the accident flight.
After the flight lost contact, a "tactical evasive action" was carried out. According to military radar data, the flight quickly rose to the altitude of 13000m after losing contact, far exceeding the flight altitude limit of this type of passenger plane of about 1. 10000m, which was suspected of "decompressing the cabin to confuse passengers" and preventing it from "communicating with the outside world". At the same time, the flight turned about 270 degrees clockwise and flew to the northwest. After that, the altitude quickly dropped to 7000 meters. At about 1: 30, many witnesses saw a passenger plane flying at low altitude, and the police in Kota Balu received four related reports.
After flying a certain distance northwest over the Gulf of Thailand, the passenger plane began to turn southwest and flew to Kota Baru. The staff on the offshore drilling platform of a European company in the north of Godabalu also reported that there were planes flying at low altitude, and the direction was southwest.
After that, the passenger plane flew over the Malay Peninsula along the border between Malaysia and Thailand. It is said that "Malaya Peninsula is mountainous, with an altitude of 1000 to 2000m, and flying at low altitude is more dangerous", and the flight once returned to the normal cruising altitude. After sailing to Penang on the east coast of the Straits of Malacca, it turned to the northwest, crossed Perak Island, and gradually lowered its flying altitude. Since then, it has disappeared from the Malaysian military radar.
At 2: 40 am, the flight briefly appeared on the military radar again. At this time, the flight was located at waypoint VAMPI, continued to fly towards andaman islands, and then disappeared from military radar again.
At 2: 53 am, Ho Chi Minh Air Traffic Control asked another Malaysia Airlines passenger plane MH386 to try to contact MH370, but did not receive a response. At 8: 00 a.m. 1 1, the flight sent the last ping data communication to the satellite, but the route and landing place are unknown for the time being. According to the red arc of the map attached to Malaysia's official statement, the flight may end between Kazakhstan, Turkmenistan and Thailand and Indonesia and the South Indian Ocean.
