Remember that the "airplanes are hijacked and flown into buildings" model was neutralized on the morning of 9/11/2001. It only worked three times, the fourth time it was attempted, that same morning, it failed. With that in mind, consider the massive overreaction to that specific type of threat. Entire government agencies were created to combat it, despite it already being solved.
