We'll never know, which is why you have every reason to be skeptical as am I. However, I think the point you need to focus on is why did BBC report building 7 down when it was still standing in the background?
"At 4.27pm, a BBC reporter, Greg Barrow, who is in New York, appears on our radio news channel, BBC Radio Five Live, and says: "We are hearing reports from local media that another building may have caught light and is in danger of collapse." He then responds to a follow-up question by saying "I'm not sure if it has yet collapsed but the report we have is talking about Building 7."
At 4.53pm, on the same radio station, the programme's presenter, Fi Glover says "25 minutes ago we had reports from Greg Barrow that another large building has collapsed just over an hour ago."
At 4.54pm, the BBC's domestic television news channel, BBC News 24, reports the same thing. Presenter Gavin Esler says: "We're now being told that yet another enormous building has collapsed... it is the 47-storey Salomon Brothers building."
And then at 4.57pm on BBC World (according to the clips available on the web) presenter Phil Hayton says: "We've got some news just coming in actually that the Salomon brothers building in NY right in the heart of Manhattan has also collapsed."
Because three BBC channels were saying this in quick succession, I am inclined to believe that one or more of the news agencies was reporting this, or at least reporting someone saying this.
At 5pm, News 24 repeated the news in its top-of-the-hour headlines sequence and then at about 5.10pm (again according to the clips on the web), Phil Hayton on BBC World says "More on the latest building collapse in NY - you might have heard I was talking a few moments ago about the Salomon building collapsing and indeed it has... it seems this wasn't the result of a new attack but because the building had been weakened during this morning's attack."
Some of the respondents to my earlier blog have suggested this must mean he had inside knowledge - that not only did he know the building had collapsed, he knew why.
Well in one sense that's true - for about an hour, it had been reported that the building was on fire and in danger of collapse. But he did qualify it by saying "it seems" and once again I think there's a danger of reading too much into what I believe was a presenter merely summarising what everyone had been saying during the previous hour.
Of course, with hindsight we now know that our live shot showed the building still standing in the background. But again I point to that confusing and chaotic situation on the ground - the CNN reporter who had talked about the building "either collapsed or is collapsing" also had it clearly in shot behind him, but he acknowledged he couldn't see very clearly from where he was standing. As we know, the building did collapse at 5.20pm, with the first pictures of that being broadcast on News 24 at about 5.35pm."
