Security by obscurity

Detroit Free Press, August 12, 2006:

Northwest Airlines urged passengers Friday to avoid carry-ons and instead check all bags, in order to speed up security lines and boarding.

USA Today, March 20, 2006:

Airlines worldwide lost a record 30 million bags last year, a number boosted by a global surge in travelers, a study issued Monday says.

Last year, the world's airlines boarded about 2 billion passengers who checked 3.7 billion bags, according to the study from SITA, a Switzerland-based technology consultant for the airline industry. Airlines mishandled about 1%.

I guess that's one approach to airline security...
