Not using protective equipment when gliding at high altitude is extremely dangerous behavior. It is strongly recommended to use appropriate protective equipment, such as helmets, protective gear, paragliding, etc., at all times. Protective equipment is the basis for ensuring safety, and no skill can replace the protective effect of equipment. If you have to perform high-altitude gliding without protective equipment in extreme circumstances, the following are some **theoretical techniques**, but please note that these techniques do not completely eliminate the risk, and the possibility of falling is still very high.： 1. **Choose a suitable landing site**： - Try to choose flat, soft ground, such as grass or sand, and avoid hard ground or rocks. - Avoid places with obstacles, such as trees, buildings, or power lines. 2. **Control gliding speed and direction**： - Try to maintain your body balance and avoid spinning or tumbling out of control. - Try to slow down the falling speed by adjusting your body posture. 3. **Posture when landing**： -Try to land with both feet first, bend your knees slightly to absorb the impact. -Avoid supporting the ground directly with your hands, which may cause wrist or arm injuries. - Try to roll your body as much as possible to disperse the impact. 4. **Stay calm and focused**： -Panic will increase the risk of injury, try to stay calm and focus on the landing process. 5. **Plan ahead**： -If possible, observe the terrain in advance and plan the gliding route and landing site. **Once again, **, These techniques do not completely eliminate risks. High-altitude gliding is a high-risk activity in itself. **The use of protective equipment is the only reliable way to ensure safety.**. If you lack the necessary equipment or experience, it is strongly recommended not to try high-altitude gliding, so as not to cause serious injury or even life-threatening. Safety always comes first!
