Un EDIFICIO va a DERRUMBARSE sobre la ciudad y NADIE lo sabe… esto pasa minuto a minuto

A skyscraper in the heart of Manhattan had a design flaw that could have caused it to collapse onto the city… and nobody knew. In 1978, the Citicorp Center concealed a structural defect that could turn a storm into a catastrophe. In this MEGAFALLA video, we reconstruct the Citicorp Center case minute by minute: the design based on unusual columns, the error with diagonal bracing, the bolted connections, William LeMessurier's discovery, Hurricane Ella, and the secret repairs carried out at night while thousands of people continued using the building, unaware of the risk. Megastructures, hidden systems, and real engineering failures explained with tension, context, and clarity. Subscribe to MEGAFALLA to discover what happens when engineering is pushed to its limits. #MEGAFAULT #CiticorpCenter #Skyscrapers #Manhattan #Engineering #EngineeringFails #NewYork #Megastructures #HiddenSystems #MinuteByMinute
