"Flying and Driving after the September 11 Attacks," by Michael Sivak andMichael J. Flannagan. AmericanScientist, January-February 2003, pages 6-8.

Sivak and Flannagan use some basic statistics to compare the risks involved inflying to those involved in driving.

The methods usedand assumptions made in the investigation are clearly stated so anyoneinterested in making a more precise assessment of the risks could.
