Сделайте хороший перевод, плииииз!!!!! 

The Last Inch (by James Aldridge, adapted) It wasn't easy for Ben, a pilot of forty-three, to find a flying job. That's why it was a stroke of luck when he was offered a job by the Commercial Television Stock Company. They paid a thousand dollars for every five hundred feet of shark film. Ben used a light plane to get to a little desert island in the Red Sea where the water along the coast was always filled with good-sized sharks. Ben took his ten-year-old son Davy with him. He was a shy quiet boy who had never been particularly loved by his parents. While filming the sharks, Ben was attacked by a huge tiger shark. He was lucky to get out of the water, but his body was a bleeding mess. He couldn't feel his arms or his feet. He had lost a lot of blood and was in and out of consciousness. The boy had to either fly the plane or die from thirst and the hot sun on the island where nobody would ever find them. Only once had Ben shown the boy how to fly a plane. He also explained that it was the last inch above the ground that mattered if the plane was going to crash while landing or not. What finally awoke Ben was the engine coughing. "Please wake up!" shouted Davy. "What's the matter?" "Push the lever forward," whispered Ben. Davy couldn't have known about the lever and now Ben wasn't able to point to it.
