11 september på SVT. Varför nämner dom inte tredje tornet?

On September 11, 2001, the structure was substantially damaged by debris when the nearby North Tower of the World Trade Center collapsed. The debris ignited fires on multiple lower floors of the building, which continued to burn uncontrolled throughout the afternoon. The building's internal fire suppression system lacked water pressure to fight the fires. The collapse began when a critical internal column buckled and triggered cascading failure of nearby columns throughout, which was first visible from the exterior with the crumbling of a rooftop penthouse structure at 5:20:33 pm. This initiated progressive collapse of the entire building at 5:21:10 pm, according to FEMA,[5]:23 while the 2008 NIST study placed the final collapse time at 5:20:52 pm.[6]:19, 21, 50–51 The collapse made the old 7 World Trade Center the first steel skyscraper known to have collapsed primarily due to uncontrolled fires.[7][8]
