Steve Lemons of the Phoenix New Times takes a look at conspiracy theorists’ claims and Debunking 9/11 Myths:

“It's easy to regurgitate a tangled fur ball of distortions about 9/11. Disproving them almost requires a Ph.D. in structural engineering.

“With the gall of Holocaust deniers Knudson, et al., claim the collapse of the Twin Towers was because of a secretly implemented ‘controlled demolition.’ Temperatures from fires resulting from the crashes of two Boeing 767s were not hot enough to melt the towers' steel columns they argue. Videos of the towers falling supposedly show a controlled demolition under way.  PM makes Swiss cheese out of this crackpottery.”
