9/11: Tag der Verschwörungen?
04.09.2008 um 11:10"World Trade Center Debris:
After the attack, fire and subsequent collapse of the Twin Towers on September 11 2001, the colossal pile of debris left on the site smouldered (smoulder == schwelen) for more than five months. It resisted attempts by fire fighters to extinguish it (to extinguish it == es zu _löschen_) until most of the rubble was removed. The effects of the gaseous and aerosolized products of smouldering (The effects of the gaseous and aerosolized products of smouldering == Die Auswirkungen der gasförmigen und ärosol-förmigen Produkte des _schwelens_) on the health of the emergency workers were significant but the details are still a matter of debate.

es war also kein Schwelbrand im Ground Zero, sondern ...
Schwelbrand erreicht max. 600 Grad C:
The fundamental difference between smouldering and flaming combustion is that smouldering occurs on the surface of the solid rather than in the gas phase. The characteristic temperature and heat released during smouldering are low compared to those in the flaming combustion (i.e., ~600°C vs. ~1500°C). Smouldering propagates in a creeping fashion, around 0.1 mm/s, which is about ten times slower than flames spread over a solid.
