Recently, winged flight has caused a lot of discussion. The news that a girl flying with wings died unexpectedly swept our circle of friends and Weibo, and everyone was discussing the sport fiercely. While regretting her unfortunate death, everyone wondered why she didn't choose to open the parachute at the last minute. You may not know the difficulty of winged flight, but its mortality rate is as high as 30%, and it is a sport with the highest risk factor. No more than 1000 people in the world can fly independently. So, everyone can know how challenging it is. The girl chose Zhangjiajie as the take-off place, and the situation in Zhangjiajie is very complicated. The weather changes quickly. There is no way to prevent it, so the sudden change of local weather in Zhangjiajie, such as wind shear, may have caused this tragedy, which is beyond the girl's control over the wing suit. Another possibility is that the female student fainted during the take-off flight, which made her unable to open the parachute. A video recorded the photographer who parachuted with the girl calling her to open the parachute, but she didn't respond and fell straight. So it can be speculated that she has fainted at this time. Another possibility is that the parachute is broken, because there is no way to guarantee the integrity of the parachute. However, as a winged flying enthusiast, I should check the parachute and other equipment before taking off, because I personally think this possibility is relatively small. We should learn from this tragedy. We can't evaluate what the girl has done. Extreme sports are her hobby. However, as a bystander, we can get some enlightenment and thinking from this case. Life is beautiful, we have different pursuits, but we should also pay attention to our own life safety in this process.
