Why didn’t Liu An open his parachute when he was flying in a wingsuit in Tianmen Mountain?

Liu An, a female college student who flew in a wingsuit in Zhangjiajie, was found on the sixth day after losing contact. Unfortunately, a miracle did not happen, which is regrettable! According to reports, Liu An's parachute did not open. Until the official announcement of the real cause of the crash, we can only make guesses.

The parachute did not open

According to official media reports, Liu An’s parachute did not open. This of course means that the parachute did not open. It does not include that the parachute was pulled but the parachute was not fully opened. Otherwise, the parachute would be visible at the crash site. If the parachute did not malfunction, then it must be that Liu An did not open the parachute at all.

Even if the parachute fails, this factor cannot explain the deviation of Liu An’s front wingsuit flight from the planned route. Therefore, the explanation of parachute failure cannot be the only factor in Liu An’s accident, and we will not analyze this probability. factors, then it can only be that Liu An did not open the parachute at all. In this case, there are many possibilities that Liu An did not open the parachute.

Villers' descriptions

It was local villagers who first discovered Liu An. Liu An lost contact on May 12. According to the villagers' descriptions, they carried water and milk along the way, and they themselves I was reluctant to drink it when I was thirsty, hoping to leave it to Liu An after I found her, but unfortunately the miracle did not happen.

According to the descriptions of the four of them, they set out at 6 o'clock in the morning on May 18 to search the front mountain of Tianmen Mountain. They divided into two groups after reaching the middle of the mountain. Finally, at about 10 o'clock, At that time, Liu An was found, his body was covered with messy branches, and his fall location was on the ridge on the left side of Tianmen Mountain.

There is a key piece of information in the villager’s description (original words): “She probably flew too low and wanted to go around the gap and land in the front parking lot, but she was unlucky there. , maybe one or two meters lower, and hit the tree, which is very critical. After breaking the branch, the person was unfortunately killed..."

The villagers’ grasp of the situation at the scene must be relatively accurate. Based on their descriptions and the analysis of Liu An’s crash site, it is very likely that Liu An had controlled his flying attitude at the last moment and tried to fly. After crossing the ridge, we landed in the front parking lot (after flying over the ridge, there was a large open space). Unfortunately, the height was only one or two meters short. In the end, we unfortunately hit a branch and died on the spot (it can be seen from the branches on the body that after falling, and no trace of movement).

Analysis of the fall process

Assuming that the situation we have is true and the various guesses are correct, then we can try to restore the process of Liu An's accident:

Liu An After arriving at the predetermined location by helicopter with the photographer, the two left the helicopter one after another for wingsuit flight. According to the pre-designed flight route, the two of them should fly to the right. At this time, the two encountered strong airflow. The photographer relied on his own experience She quickly entered the headwind and gained enough lift, but Liu An was deflected by an updraft to the left. About 19 seconds after leaving the plane, the photographer waved to An An (perhaps signaling her to open her umbrella or motioning her to the right). flight).

At this time, Liu An was also trying to adjust her posture, trying to return to the pre-designed route, but the airflow Liu An was in was too strong, and she was getting farther and farther away from the photographer, and then she encountered A strong downdraft (wind shear) caused a loss of a lot of altitude in just a few seconds. Perhaps she thought the altitude was still within a controllable range, so she did not open the umbrella. As the altitude decreased, the airflow weakened, and Liu An also She quickly controlled her flying attitude and transitioned into a gliding attitude. At this time, she had changed from a relatively safe high-altitude wingsuit flight to a high-risk low-altitude wingsuit flight.

At this time, 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 is faced with two choices:

Choice one: Open your parachute immediately, then land in the mountainous area and wait for rescuers.

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

You must know that Liu An did not carry a positioning device or any communication equipment this time. Perhaps out of confidence, he considered that if he landed in a mountainous area, the risk would be great. Since he was certain to cross the ridge, then In such a situation, people would instinctively tend to the second option, and Liu An also chose to do this. Unfortunately, the airflow in the mountainous area was too complicated, and too much height was lost in front. The difference was only one or two meters. Unfortunately, in the end She hit a branch and fell to the ground, with scattered branches falling on her.

The above analysis is just a guess, a possibility based on the information currently available; the real situation requires more information to speculate. For example, Liu An was carrying a video recording device with him at the time. , but these videos still need to be analyzed by the police and authorities before they can decide whether to publish them.
