a Businessweek article claims that airport security is killing us:

There is lethal collateral damage associated with all this spending on airline security—namely, the inconvenience of air travel is pushing more people onto the roads. Compare the dangers of air travel to those of driving. To make flying as dangerous as using a car, a four-plane disaster on the scale of 9/11 would have to occur every month, according to analysis published in the American Scientist. Researchers at Cornell University suggest that people switching from air to road transportation in the aftermath of the 9/11 attacks led to an increase of 242 driving fatalities per month—which means that a lot more people died on the roads as an indirect result of 9/11 than died from being on the planes that terrible day. They also suggest that enhanced domestic baggage screening alone reduced passenger volume by about 5 percent in the five years after 9/11, and the substitution of driving for flying by those seeking to avoid security hassles over that period resulted in more than 100 road fatalities.

It’s certainly true for me: since 2001, I always choose to drive rather than fly if I have any way to make my schedule accommodate the extra time. I’m going down to California for a Christmas visit and you can bet I’ll be taking the car.
