A Stinger missile launched from a hotel room window overlooking an airport (think of San Diego, for example, as the fllight path comes in over the downtown skyscrapers) would halt air traffic--again. Especially if several attacks happen at about the same time. Half a dozen Western airline companies have already gone into bankruptcy--another sharp falloff in bookings will likely send a dozen more into liquidation.
Andrews Air Force Base, or wherever it is Air Force 1 flies out of, would be interesting as well....
