Title: The riddle of the Leaning Tower
Description: To save the Leaning Tower of Pisa from further leaning and eventual collapse, the Italian government appointed a scientific committee to devise a solution.  This program documents the committee's activities in the 1990s: discussions, building and soil analyses, and controversial answers to the structure's ongoing decline, from the weights placed on the rising north side in 1993 to the 1999 soil extraction procedure.  Includes interviews with John Burland, professor of geotechnics at the Imperial College of Science and Technology, London, Piero Pierotti, professor of medieval architecture at the University of Pisa, Carlo Viggiani, University of Napoli Federico II, Italy, and Giorgio Macchi, professor of structural engineering at the University of Pavia.
