Diane Hartley asked a critical question about the design of the Citicorp Center skyscraper in New York City that caused the design engineer to realize that they had made a mistake. The building was already occupied and immediately went under secret repairs to restore the capacity. This is an amazing story that is used in many classes to teach about engineering ethics, design, and the importance of asking questions. In this video we get to hear Diane’s version of the story and how she learned about the repairs and how her work contributed to saving this important structure. This is truly an amazing story and it is awesome that we get to hear it from the person that lived it.
