Firefighters 9/11 Documentary - Calling Out Bravo 7 - The 2020 Edition

Firefighters talk about fire physics, building designs and explain why they continue to commit into high-rise fires without fear of sudden and complete building failure. The science of fire behaviour and basic physics is used to show how normal office fires cannot create the same outcome observed in both a controlled demolition or the free-fall collapse of World Trade Centre Building-7 on September 11th 2001.
