Narrator:
...On October 17, 2004 a 56-storey skyscraper in Venezuela built in 1976 burned for over 17 hours and fire spreads over 26 floors, eventually reaching the roof. Guess what? It did not collapse. On February 12, 2005 the Windsor Building in Madrid, a 32 storey tower framed in steel-reinforced concrete burned for almost 24 hours, completely eradicating the upper 10 storeys of the building. Although the top 10 floors of the building fell the building itself did not collapse. And yet, on September 11, 2001 two 110 storey skyscrapers, completed in 1973, burned for 56 and 103 minutes respectively over 4 floors before collapsing completely to the ground.
