Ponemon Institute conducted a survey of laptop loss at airports in the United States and Europe [PON08]. At 36 of the largest U.S. airports they found an average of 286 laptops are lost, misplaced, or stolen per week. For eight large European airports, the figure is even larger: 474. Of these, 33 percent were recovered either before or after the flight in the United States and 43 percent in Europe.
