Have you ever been on a very turbulent flight and looked around to see someone more nervous than you? Have you seen a child with fear and terror in their eyes and Mom or Dad don't look much more confident? That was the case that inspired this story. The wife of author William Braley had given up her seat to a nine-year-old traveling with her father and was seated next to William in a flight during a really rough weather. As the girl trembled, William began telling her the story in this book, making it up as he went along. Soon, the child, her father, and some others in ear shot were his captive audience. At the end of the flight, an attendant that had overheard and shared with the pilot suggested that he write a book. The pilot thanked him and also mentioned it would be a great story to have on all flights for just such occasions. So came the book, Why Airplanes go Bump in the Clouds.
