Pourtant, le chef des pompiers de New York, le jour du 11/9, a envisagé la chute du WTC 7 et a organisé pour cette raison une "collapse zone" trois heures avant l’effondrement. Voici les raisons qu’il donne à son anticipation :
1 - Although prior to that day high-rise
structures had never collapsed, The collapse of WTC 1 & 2 showed
that certain high-rise structures subjected to damage from impact and
from fire will collapse.
2. The collapse of WTC 1 damaged portions of the lower floors of WTC 7.
3. WTC 7, we knew, was built on a small number of large columns providing an open Atrium on the lower levels.
4. numerous fires on many floors of WTC 7 burned without sufficient water supply to attack them.
