Edited sentence: As 9/11 is described, it MUST be made clear that there were historically unique circumstances, with the Vice President and the US Air Force directly in charge of all air traffic over the USA, to include all civilian flights.END NOTES.If you don't like these changes, then include this information in other form or strike all references to Al-Quaeda, the fire department's difficulties with organizational aspects on 9/11, and mayor Guiliani.It also a proper correction to replace the section about the aircraft being flown by Al-Quaeda with a simple statement that two aircraft "impacted" in the twin towers.It is a fact and not oppinion, that mayor Guiliani had placed the city's permanent emergency command and response center in the World Trade Center against advise, as the WTC had been the previous target of a successful attack in 1991.It is not a personal point of view to add "alleged" to the term "terrorists".NOTE TO THE EDITORS:.NOTE to readers:.That is fact.The allegedly highjacked aircraft were not intercepted.This article clearly references Al-Quaeda and events that were never fully resolved, neither under official Government investigations, nor in any court of law.This contributed directly to the disruption of the structure of the emergency control command chain and all the problems the article mentions above.end Note to readers
