428 Gravity

To those who really care for flying, gravity is something that one tries to escape from. But if you look at moon and stars in the sky, strangely but truly they exist, or float owing to the gravity between each other. Jumping out of one gravity means getting close to another. But if one stick to one gravity it will rotate the same circuit forever. Sometimes it will kick itself out to find a place of new balance in mutual gravity. It's so much like human relationship.
