Is there a real Chuck Noland?

The character of Chuck Noland in the movie "Cast Away" played by Tom Hanks is entirely fictional. He was created by screenwriters William Broyles Jr. and Eric Roth along with the rest of the movie's story as a work of fiction meant to entertain the audience and explore themes such as isolation, survival, and personal transformation. There's no actual person on which the character is based or was inspired by.
