[QUOTE=MNBluestater;2906898]FLYVMO, dropping a nuclear dirty bomb out a window, a bomb of ricin , or anthrax that explodes at altitude 300 ft ever occur to you...not entirely out of the realm...and it is one of the easier ways to cause terror (than trying to buy massive amounts of ammonia and fertilizer like McVey did....)QUOTE]
I think the bigger point is that for a terrorist to use a GA aircraft to create any kind of serious havoc is possible, but not at all probable. Having worked in NYC for many years, there are many easier ways of doing this without dealing with the complexity of getting an airplane. Could it happen? Sure. But there are many other possibilites that can deliver more damage with less effort, and that is where the powers that be need to focus their attention. Just watch the traffic into and out of the city's tunnels each day. Back packs on the subway system, luggage in airports before it gets checked in, unmarked repair trucks on city streets, etc. Given all of the air traffic that occurs in and over the city, I think the track record for aircraft hitting buildings is pretty low. The press is whipping this into a frenzy. Calmer minds need to prevail.
