Why did Roald Dahl become a writer?

Roald Dahl was a fighter pilot for the Royal Air Force and after a crash left him unable to fly, he turned his efforts to writing. His first story was about his wartime experiences and C.S. Forester was originally supposed to write the story, but he was so impressed with Dahl's writing that he published Dahl's version.

Some of Dahl's most famous works are the children's books "James and the Giant Peach" and "Charlie and the Chocolate Factory." He started writing children's books in 1960 and originally wrote them for his own children, but eventually took the stories to publishers.
