Rolad Dahl originally referred to his recollection of his fighter plane crash in Libya during World War II as 'a piece of cake'. However, he later made changes to the title of this particular piece. The article was renamed to 'Shot Down Over Libya'. This vivid account of Dahl's brush with death was his first published work and eventually led to his illustrious career as a writer.
