Learning to dive the Earth’s interior

X-Ray53_alpha-83

Two buddies are holding the line. The second is holding the arm of the one leading the way, communicating with him by means of touch. With visibility nil, the first buddy protects his head and face with his hand in case of contact with a wall or rock. Suddenly, for some unknown reason, the line moves and goes out of their hands. They search for it but to no effect. Their mistake: they were not holding the line properly. Will they panic? No. Their nearby instructor stops the exercise. The entire scenerio took place on dry land.
