I thought the story on 7 was that it was a shit architectural design that really wasn't designed for 47 stories and they didn't want to cause panic because there are other shit architectural designs in NYC. IIRC, there was a PBS special on a building in midtown that would collapse in a Sandy sized storm. They spent millions putting in additional supports without telling the occupants.Ben Swann recently did a report on how more Americans are having doubts on the official story, especially regarding building 7.

The engineers did not recalculate what the construction change would do to the wind forces acting on two surfaces of the building's curtain wall at the same time; if hurricane-speed winds hit the building at a 45-degree angle, there was the potential for failure due to the bolts shearing. The wind speeds needed to topple the models of Citigroup Center in a wind-tunnel test were predicted to occur in New York City every 55 years. If the building's tuned mass damper went offline, the necessary wind speeds were predicted to occur every 16 years. Should the building fall, it would kill about 200,000 people and obliterate over 100 city blocks.
