Today in America, we are trying to prepare students for a high tech world of constant change, but we are doing so by putting them through a school system designed in the early 20th Century that has not seen substantial change in 30 years.

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).

It would be unwise to say the least, irresponsible of us at the TSA, at the Homeland Security Department not to evolve our technology to match the changing threat environment that we inhabit.

One of the most striking elements of today's threat picture is that plots to attack America increasingly involve American residents and citizens.

There are a number of countries that we see cyber-attacks emanating from. And, again, they can be just individuals who are located in the country. But three that I think are of special concern would be Iran, would be Russia, and China.

You can't imagine a world, quite frankly, without a safe and secure aviation system. And so our job is to really focus on that, and what we need to do to keep it safe and secure.
