Each and every one of the security measures we implement serves an important goal: providing safe and efficient air travel for the millions of people who rely on our aviation system every day.

Each and every one of the security measures we implement serves an important goal: providing safe and efficient air travel for the millions of people who rely on our aviation system every day.

And we ask the American people to play an important part of our layered defense. We ask for cooperation, patience and a commitment to vigilance in the face of a determined enemy.

Now, a lot of what we are doing right now, quite frankly, is because of what happened on Christmas. Many of the things were kind of in the works. We were already planning, for example, the purchase and deployment of advanced imaging technology. You call them body scanners. We call them AITs (Advanced Imaging Technologies).

All images generated by imaging technology are viewed in a walled-off location not visible to the public. The officer assisting the passenger never sees the image, and the officer viewing the image never interacts with the passenger. The imaging technology that we use cannot store, export, print or transmit images.
