Zach fell through the air, over the drop-off. As he was falling, Zach looked down. To his relief, there was a river at the bottom of the chasm. Zach tried to aim himself in the dead center of the water. The wind was beating faster and faster on him, making it difficult to concentrate. But after a few seconds of free-fall, Zach hit the water, feet first. The water hit him pretty hard, but Zach maintained control. His feet touched the bottom of the river. He pushed up and reached the surface again. Zach began swimming toward the bank. Suddenly, there was a loud crash. Zach looked back up the cliff. Above him were several train cars falling off the edge.
