Oops! WTC Building 7's Collapsed Announced Way Too Early

Of the two principal theories of WTC 7's collapse -- one being global structural failure due to prior debris impact and ongoing fire damage, and the other being controlled demolition -- the second is favored by foreknowledge of the collapse. This is particularly true given the lack of precedent of total collapses of steel framed structures during fires. So unprecedented was the collapse of Building 7 that the government has yet to explain it, in 2007. That would probably be lost on most responders on the site, who would have the fresh memories of the Twin Towers' explosions to help them accept the notion that the total of collapse of smoking skyscrapers is a natural and even predictable occurrence.
Witness reports show that officials who controlled the streets around WTC 7 evacuated the area in the hour before the 5:20 PM collapse, and that various officials forwarded verbal warnings conveying certainty that the collapse would occur. Network television broadcasts contain announcements of the collapse at least 23 minutes before the event.
