Yeah, I know, another one of those 9/11 threads, but anyway:
WI, instead of merely hitting the buildings, Al-Qaeda followed up by shooting down airliners with MANPADS near major airports (JFK, O'Hare, LAX, DIA, Atlanta, Newark etc.)? The logic is that after the Twin Towers and Pentagon are hit FAA would ground all flights ASAP, and then the terrorists can maximize damage.
Is it possible? And what would the reaction be?

P.S. For the purpose of this discussion let's say a bunch of Stingers dated back to the 1980s found their way into AQ hands.
