Aww, you beat me to it..., well done.
I was listening to both tower frequencies all the time and did not hear anything. "Funny" thing is, a couple of minutes later a pilot inquired about that and the controller sarcastically replied something including the phrase " ... possibly 'terrorists' ..." (not knowing anything new; as if he had not yet received an update on the situation).
I have been looking through the archive but cannot find it.
well it was happening around 2230-2300Z time for one thing... you would have to look in the "KJFK tower all/119.1 priority" feed. I would have included some more reports in there but I couldn't get any clear ones without being inturpted by the other freq. It was on the 119.1 only feed (thats were I heard it) but I wasn't archiving right at that time...
