I seem to remember them saying this once before.
This is the second Pakistani journalist to say this, the other ones name is Mir, he was on Fox & Glenn Beck show talking about it.
I think in 2004? There was a web posting with picture of mushroom cloud over NYC. ALSO, for the first time in months, the "This is Not a Test" test came on my TV the other day. Hadn't seen them in decades until after 9/11. They were at least a few times a month for a few years, then zip. Now, they're back. I remember them vividly from my childhood (I am 42).
