At the height of 35,000 feet above sea level, the wind is blowing in all directions, creating a huge gap in the air. The air is thin at this height, and the only way to get back in is to go through the air currents. The wind pushes the air around the vehicle, which is why it is so difficult for the rider to go back in. The rider is worried that the monster is going to fly away, so he tries to catch up with him. He says that he has begun to catch "rika" , the rider's companion, who rides in a similar fashion to the rider. She is driven by "down force," which is a force that moves objects close to a wall or ground in order to raise their speed. This is why the rider is able to pass through the wall. The doctor tells the rider that the wreckage is falling down like a "blender," and the rider says that this is a sign that the wall is breaking down. He tells the doctor that it is time for him to bust it down.
