Skydivers who are below the formation can navigate through the air by using their body position to adjust their vertical speed and horizontal movement. By controlling their body's angle and surface area, they can change their direction and speed to align themselves with the group above them. Additionally, they can communicate with other skydivers using hand signals or radios to coordinate their movements and join the formation. Practice and experience in formation skydiving techniques are essential for successful air navigation and joining a group during a jump.
