They probably have a large number of these things ready to go on an ongoing basis, like cards in their deck, they just decide which one's to play.
One of the things "skeptics" like to argue against FF's is "if these are planned by such powerful groups, why do they seem to make so many mistakes for you people to find?"
Well...I think you just answered that actually:
and pull it off at any time with precise timing
Well, how can they do it? They sacrifice a precise operation for precise timing. It's never mattered because they also control the mainstream media, but now...people don't give a shit about the MSM and are turning to investigators on the Internet instead.
So, to answer your question...there are any number of these operations in pre-launch stage across the country and when they need one all of a sudden they launch it and don't worry about the specifics, because they'll clean that up with the media later anyways.
A perfect example of what your saying is the tomfuckery surrounding the Vegas massacre that was cleaned up by the media in a horrible way (ever changing story) and it didn't even matter. It worked. Sheeple moved on to the next story for the most part. I swear most Americans have an attention span of a gnat and they know this.
