On July 17, 1981, two walkways collapsed at the Hyatt Regency Kansas City hotel in Kansas City, Missouri, one directly above the other. They crashed onto a tea dance being held in the hotel's lobby, killing 114 and injuring 216. As a product of a corporate culture of profound neglect, the disaster contributed many lessons to the study of engineering ethics and errors, and to emergency management. The event remains the deadliest non‑deliberate structural failure in American history, and it was the deadliest structural collapse in the U.S. until the collapse of the World Trade Center towers 20 years later.
