Liu An, a female college student who spread her wings and flew in Zhangjiajie, was found on the sixth day. Unfortunately, there was no miracle. What a pity! It is reported that Liu An's parachute did not open, so we can only guess until the official announcement of the real cause of the crash.

The parachute didn't open

According to official media reports, Liu An's parachute didn't open, which of course means that the parachute didn't open, not including the situation that the parachute didn't open completely when the parachute device was pulled open, otherwise the parachute could be seen at the crash site. If the parachute didn't break down, it must be that Liu An didn't open it at all.

Even if the parachute fails, this factor can't explain that the winged flight in front of Liu An deviated from the planned route, so the explanation of parachute failure can't be the only factor of Liu An's accident, and we don't analyze this probability factor, so it can only be that Liu An didn't open the parachute at all, which is more likely that Liu An didn't open the parachute.

Village description

Liu An was first discovered by local villagers. May 12 Liu An lost contact. According to the villagers, they took water and milk along the way, and they were reluctant to drink when they were thirsty. They hoped to find Liu An and leave it to her, but the miracle didn't happen.

According to the descriptions of the four of them, in May 18, they set off at 6: 00 in the morning, searched in front of Tianmen Mountain, divided into two groups halfway up the mountain, and finally found Liu An around 10, covered with messy branches, and fell on the ridge on the left side of Tianmen Mountain.

In the description of the villagers, there is a key message (original words): "She should have flown too low and wanted to bypass this gap and land in the parking lot in front, but that place was unlucky. Maybe it fell a meter or two and hit a tree, which is very important. Then she broke the branch and died ... ".

The villagers' knowledge of the scene must be accurate. Through their description and analysis of the crash site in Liu An, it is likely that at the last minute, Liu An had controlled his flight attitude and tried to land in the front parking lot after flying over the ridge (there was a large clearing after flying over the ridge). Unfortunately, it was only one or two meters away, and finally it hit a branch and died on the spot (as can be seen from the branch on his body, there was no trace of movement after falling).

Falling process analysis

Assuming that everything we know is true and all kinds of guesses are correct, then we can try to restore the process of the Liu An plane crash:

Liu An and the photographer arrived at the scheduled place by helicopter, and left the helicopter for wing-mounted flight. According to the pre-designed flight route, they should fly to the right. At this time, they met a strong airflow. The photographer quickly entered the upwind airflow based on his own experience and gained enough lift, but Liu An was deflected to the left by an updraft. After leaving the plane for about 19 seconds, the photographer waved to Ann (perhaps to signal her to open the umbrella or to fly to the right).

At this time, Liu An is also trying to adjust his posture and try to return to the pre-designed route, but the airflow in Liu An is too strong and he is getting farther and farther away from the photographer. Then, she encountered a strong downward airflow (wind shear) and lost a lot of height in just a few seconds. Maybe she thought the altitude was still under control, so she didn't take an umbrella. As the altitude decreases and the airflow weakens, Liu An quickly controls the flying attitude and turns to gliding attitude. At this time, she.

At this point, the photographer has completely left Liu An's field of vision. Liu An must be thinking about how to land safely. At this time, she was faced with two choices:

Option 1: Open the umbrella immediately, then land in the mountain area and wait for the rescuers.

Option 2: cross the front Tianmen Mountain ridge, then land in the front open space, or even land directly in the parking lot.

You know, Liu An didn't carry a positioning device or any communication equipment this time, probably out of confidence. Considering that if he lands in the mountains, the risk is also great. Since he is sure of the hurdle, in this case, people will instinctively tend to the second option, and Liu An chose to do so. Unfortunately, the airflow in the mountain area is too complicated, and he lost too much height in front, only one or two meters away. In the end, he unfortunately hit a branch, fell to the ground and splashed.

The above analysis is only a guess, which is a possibility based on the information currently available; The real situation needs more information to speculate. For example, Liu An took video equipment with him at that time, but these videos need to be analyzed by the police and authorities before deciding whether to publish them.
