Final answer:
Without the title and author, the chapter and its author cannot be identified. The pilot was flying an old Dakota aeroplane and was not described as unhappy, contrary to the information provided. He saw the lights of a big city in front of him, possibly Paris.
Step-by-step explanation:
The passage provided is from a narrative text, but without the title and author, we cannot identify the chapter and its author. The aeroplane mentioned is an old Dakota, which the pilot was flying over France back to England. The text does not explicitly mention that the pilot was unhappy; rather, it states he was 'happy to be alone high up above the sleeping countryside.' In front of him, he saw the lights of a big city, presumed to be Paris since he thought about contacting Paris Control.
