The reporter was using Extra Sensory Powers. Its a well know fact that the BBC has been way out in front of US Media outlets in the use of ESP to scoop us time and time again. Or maybe why they knew it was coming was because they thought it was a slow news day and blew it up themselves to spice things up a bit?
I'm sure a little more digging will come up with some coincidence somewhere that through some convoluted series of half truths, anomalies, urban myths, etc will prove that this is further proof of a really insanely complicated plot by our government, the media, the jews and the free masons to blow up these buildings and blame it on the terrorists. Then, you just need to play 6 degrees of the White House to find someone at the BBC that has some relationship with someone important and that will be seen as the link that proves that this MUST be true. That makes much more sense than say the reporter getting a tad confused and reporting that the tower has fallen instead of is going to fall or might fall, or the video being doctored to show the reporter reporting 15 minutes later than the background. But once you go down that path of coming up with logical - although much more boring explanations, you just open up the door for whack jobs to come up with thousands of other anomalies that may never be explained. That is precisely how conspiracy myths get steam and why every major catastrophe, assassination in American history has at least one usually several complex conspiracies attached to them. To deny them or to explain why they are ridiculous is to give them credibility.
No one who really believes in these conspiracies will ever accept the reality. I don't think these people are dangerous or deranged. And, I'm not sure paranoia is the complete answer either. But there is something in them that makes them desperate to believe in a reality where our government or the mafia or something with some type of order is behind these things. Randomness of mass violence or violence by forces beyond "our" control is a reality they cannot accept. Having a conspiracy plot that follows their own beliefs of who is bad/good restores order to their lives. They can also tie in the details or the event that maybe can't be explained to create more order with an alternate explanation. It might be caused by the trauma of the event itself. I dont know. But I think it would be a fascinating study.
