Have you ever dreamed to fry sky with just yourself? I'd dreamed that when I was child. But in the world, there are such an extreme sport. As you may know, you know sky diving, don't you? But do you know freefall? It is a style of sky diving. In freefall, you jump on your first jump from 15,000ft. A skydiver break the soud barrier with he or she dive from above it. Of course, it's so dangerous action. I wonder there are people who tried it. But they might wanted to fly sky with just themselvs even if they hurt. I'm a chicken, so I don't want to try it. However it's good opportunity to your dream that fly sky come true!
