According to the Global Network Express News on November 21, on the night of November 17, the F-16 fighter jet (no. 6672) piloted by Captain Jiang Zhengzhi of the 26th Combat Team of the 5th Mixed Tactical Fighter Wing of the Taiwan Army lost contact four days later. The specific location of the -16 fighter has been searched, and the water depth of the wrecked sea area reached 1,000 meters.
The Taiwan Army’s search and rescue forces received weak FDR beacon signals from the fighter’s black box (flight data record) for two consecutive days. After cross positioning, the detailed location of the crashed fighter has been calibrated. This beacon signal is emitted by a flight data recorder, which is called a flight data recorder (FDR).
At present, the salvage ship has left Hualien Port and is ready to conduct underwater detection and photography. After the F-16 fighter plane's accurate position on the seabed is determined, the salvage will begin. The Black Hawk search and rescue helicopter and the S-70C anti-submarine helicopter also cooperate in salvage. However, the sea conditions in the wrecked sea area are very bad recently. The strong currents have caused difficulties in the operation of detection instruments and underwater cameras, and the operation is extremely difficult. Specific salvage operations need to be suspended.
The F-16 fighter jet was introduced by the Taiwan military from the United States in the 1990s and has served in Taiwan for 23 years. However, in the 23 years of service, F-16 fighter jets have been in constant trouble, and 8 of them have crashed, resulting in the death of 8 pilots.
The aircraft crashed about 8 nautical miles off Taiwan’s Hualien. According to Taiwan’s final radar images, the F-16 fighter jet fell into the sea while flying through clouds during a confrontation exercise. At that time, the pilot did not report any mechanical failure by radio. There is also no pull up or ejection action, which can basically be determined as a "space fascination" caused by weather.
Although the crashed fighter pilot Jiang Zhengzhi was a colonel, he was 44 years old and had a total flying time of more than 2,230 hours. He had relatively rich flying experience. But before the colonel pilot fell into the sea, he probably didn't know that a serious reverse error had occurred in his flight attitude.
This is the flight data recorder (commonly known as the black box), and its appearance is usually red, not the legendary black. The flight data recorded by the black box includes the voice call recording, the backup trajectory of the attitude sensor, and the data is usually stored in a magnetic tape. It is protected by a sturdy casing outside. It has its own beacon machine, and can automatically transmit wireless to the outside world for a period of time after a plane crash. Telecommunications standard new number. Usually the black box signal of a large civil airliner can last for 30 days.
After preliminary investigations, the Taiwan military believes that the possibility of mechanical failure of the F-16 fighter is relatively low, and it is likely that the illusion of space has caused the crash. Outside military experts generally agree with this statement. Think this inference is reasonable. Although the crashed F-16 fighter was 23 years old, it had just completed technical repairs not long ago. The overall technical status of the aircraft should be relatively reliable.
When the aircraft lost contact, it was undergoing night combat combat training. The Taiwan military previously announced the video recording of the head-up display of the friendly aircraft during the combat training of the 26th combat team, indicating that the operating environment of several fighters was dark at the time. F-16 The fighter plane carried out cloud-piercing actions during the climb, and made many complicated turns in the clouds. At this time, the weather conditions are bad, and the clouds on the sea are low. The pilots are prone to illusions and are unable to grasp the true altitude and posture of the aircraft, causing the space to become lost and fall into the sea.
It is not uncommon for a fighter jet to crash into the sea due to space obsession. In August last year, the Japanese Air Self-Defense Force Misawa Base (Aomori Prefecture) had an accident where an F-35A stealth fighter crashed in the Pacific Ocean. This time, it was also an accident caused by a low cloud cover.
Since the final trajectory of this F-16 was from a height of 2100 meters to a height of 0 meters in 20 seconds, the descent rate was 105 meters per second, and the dive speed was about 900 kilometers per hour. High-speed entry into the sea would cause the fighter jet to disintegrate instantly. Therefore, according to analysis, the Taiwan military may not be able to salvage a complete body under water, and there is little hope of finding the remains of the pilot.
