Here is a picture of building 7 at 3pm on September 11,
two and a half hours before it collapsed. The lower portion of the building is darkened from the reflection of the other smaller building across the street. The only fires are on the 7th and 12th floors and are so small they could have been put out by the office sprinkler system.
"I remember getting a call from the, uh, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, 'You know we've had such terrible loss of life, maybe the smartest thing to do is, is pull it.' Uh, and they made that decision to pull and then we watched the building collapse."
Vraagje: is het mogelijk om op een paar uur tijd een gebouw van 50 verdiepingen te prepareren voor een succesvolle controlled demolition?
