I have encountered the term in another context. > A "skyhook" is an imaginary device for hanging an object from the sky. The word originated in a sarcastic remark by a frustrated pilot of a reconnaissance plane in the First World War, when told to stay in the same place for an hour: "This machine is not fitted with skyhooks," he replied.
