Skyhooks were first described in a paper entitled "Satellite Elongation into a True "Sky-Hook"" by John D. Issacs, Allyn C. Vine, Hugh Brander, and George E. Bachus on pages 682-3 of Science volume 15, February 1966. Of the six materials discussed only a diamond was found to be suitable (Carbon fibre might work but was not available at that time). When the paper was submitted many reviewers found it to be lacking in merit, but the editors did publish it with a warning that it was not practical and would be a technology for the future. While the paper discusses the physics of the materials they point out that the construction of a sky-hook would be much more complex.
