Deletion of List of fictional airborne castles

Comment: for now, since airborne castles are key elements both in a very famous fairy tale (Jack and the Beanstalk) and in one of the most popular films of all time (''The Empire Strikes Back''). It could improve if it was transformed from a list to a decent article, called Airborne castles in fiction, dealing with the subject in a more encyclopedic way. I think it is likely that if one looks for them, one could find reliable sources on the subject. Remember, |there is no deadline
