This was a test run...but supposedly a computer (that was confiscated) shows flights that they were looking into possibly hijacking, so to say that someone already knows the flight they would've been on was for certain one of the targeted flights seems a little absurd...I'm sure that knowledge hasn't been leaked yet.
I'm not discounting the possibility of it being one of those flights but no way in he11 could they know which ones it would've been.
