Airport Insecurity

Some travelers may be worried about security at U.S. airports.

The Government Accountability Office says investigators passed undetected through Transportation Security Administration checkpoints at several airports with bomb-making components concealed in their luggage and on their persons.

They also tested devices made from those components and found a terrorist could damage a plane and threaten passengers.

Testimony on the issue will be delivered Thursday to the House Committee on Oversight and Government Reform.
