A structural failure leads to the collapse of a walkway at the Hyatt Regency in Kansas City, Missouri, killing 114 people and injuring more than 200.

On July 17, 1981, two overhead walkways in the Hyatt Regency Hotel in Kansas City, Missouri, collapsed, killing 114 people and injuring 216. Loaded with partygoers, the concrete and glass platforms crashed onto a tea dance in the lobby. The collapse resulted in billions of dollars of insurance claims, legal investigations, and city government reforms.
