The following may be of value for tracking down false stories:

I notice that you cited the snopes.com/Urban Legends site to dispel and clarify the rumours about the CNN-using-old-Palestinian-footage story. There is more explanation of the "radio blacklist" story, there, too. You would do a great service by circulating the Web address for the special Urban Legends page devoted just to terrorist attack-related stories. (Every time I get that freaking Nostradamus thingy forwarded to me, I send back this address ...)
