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.

Nonetheless, to the extent that terrorists have come into our country or suspected or known terrorists have entered our country across a border, it's been across the Canadian border. There are real issues there.

The United States and Arizona are both losing jobs to offshore locations.

I'm angry that the private sector, which is supposed to be in charge of running gasoline into the Valley, doesn't have its act together to deal with a critical situation, so now the public sector has to step in.

We have at least 125 communities in Arizona at risk from wildfire, not because of review processes or litigation delays but because of a lack of federal funding on the ground to actually begin the projects.

Public schools were designed as the great equalizers of our society - the place where all children could have access to educational opportunities to make something of themselves in adulthood.

And I am also here to say that if something were to happen, we are prepared to respond swiftly, to respond effectively, and to respond strongly. That is our tradition as a country. And that is a tradition that we will uphold, regardless of any circumstance because this nation is one that is very, very strong and, indeed, extraordinarily resilient.

I've appointed a task force to take a fresh look at the color-code system and whether we should retain it, change it or scrap it.

Let me be very clear: We monitor the risks of violent extremism taking root here in the United States. We don't have the luxury of focusing our efforts on one group; we must protect the country from terrorism whether foreign or homegrown, and regardless of the ideology that motivates its violence.

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.

What we're doing is making sure that we have a safe and secure border region from San Diego all the way to Brownsville. And that means manpower, it means technology, it means infrastructure, it means interior enforcement. All, you know, kind of layered in appropriate ways, and making sure, like I said before, the border is safe and secure.

The last thing the Department of Homeland Security is about is infringing on anybody's constitutionally protected rights.

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).

But my view is that you need a system at the border. You need some fencing but you need technology. You need boots on the ground. And then you need to have interior enforcement of our nation's immigration laws inside the country. And that means dealing with the employers who still consistently hire illegal labor.

Well, you know, the violence is mostly in Mexico itself, at least the violence that people are worried about. And so we want to make sure that violence does not spill over into our communities that are along the border.

The great thing about this town hall format is that it allows us to hear what's on the minds of Americans. Tonight, it was clear - voters have quite a few questions about the direction in which the current administration is headed.

Well, you know, I think in conversations with members of the Senate and others, they all recognize that the issue of immigration is important. It's important to our nation, it's important to our public safety, it's important to our security, it's important to our economic well-being moving forward. And it's not something that's going to go away.

We've probably gotten 500 calls from people saying what the heck is going on with gas, and I gotta say I agree with you. What the heck is going on with gas?

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.

Smart businesses do not look at labor costs alone anymore. They do look at market access, transportation, telecommunications infrastructure and the education and skill level of the workforce, the development of capital and the regulatory market.

As part of our layered approach, we have expedited the deployment of new Advanced Imaging Technology (AIT) units to help detect concealed metallic and non-metallic threats on passengers. These machines are now in use at airports nationwide, and the vast majority of travelers say they prefer this technology to alternative screening measures.

So not only do we need to deal with threats as they emerge, we have to be thinking in anticipation of future threats, and the things we do have to be things that enable the system to continue to work.

If American schooling is inadequate now, just imagine how much more obsolete it will be when today's kindergarten students graduate from high school in just 12 years.

I have long been a proponent of a guest-worker program between the United States and Mexico, and in particular I have proposed that Arizona would be an ideal location for a pilot project.

We are on the lookout for criminal and terrorist activity but we do not - nor will we ever - monitor ideology or political beliefs. We take seriously our responsibility to protect the civil rights and liberties of the American people, including subjecting our activities to rigorous oversight from numerous internal and external sources.

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.

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.

I used my aviation contacts to open a travel agency. I used to book Caribbean flights.

Aviation is proof that given, the will, we have the capacity to achieve the impossible.

In the early 1930s, flying from England to Australia was the longest flight in the world. It was considered extremely dangerous and hazardous, pushing pilots to the limits of mechanical skills and human endurance. Aviation was young.

More than 60,000 jobs have been lost in the commercial aviation industry in the United States since 1999.

The mastery of the turn is the story of how aviation became practical as a means of transportation. It is the story of how the world became small.

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.

I always felt Jimmy was trapped in Hollywood. He felt it himself. He loved aviation so much and he wanted to be able to do more of that. He somehow just got stuck here.

This is a Solo Flight, but I want aviation enthusiasts and adventurers everywhere to join me in the endeavour.

I went to the University of Washington as a physics and astronomy major. My other interest, of course, was aviation. I always wanted to be a pilot. And if you're going to fly airplanes, the best place to be is the Air Force.

We continue to subsidize highways and aviation, but when it comes to our passenger rail system, we refuse to provide the money Amtrak needs to survive.

The 20th Century was the century of Aviation and the century of Globalization. The next century will be the century of Space.

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.

Aviation - and space travel, in particular - have always been especially captivating.

I was a big aviation buff as a boy.

I'd manufactured more gearboxes probably in the aviation industry than anybody else.

I'm not an aviation historian, I'm not an Air Force aficionado, and I'm definitely not a ufologist. I'm not someone who studies UFOs.

If you go back to the early days of aviation, the guys designing it built it, and then they got in it and flew it. I mean, who does that anymore?

In the U.S., the term 'general aviation' means its exact opposite, the way 'public school' does in England. An English public school is private and, on top of that, exclusive. Likewise, general-aviation airports in the U.S. are for everyone but the general public.

Medical professionals are as skilled and as dedicated as any, but they operate within a fragmented system that has not progressed as far as we have in aviation.

Non-commercial general aviation flights serve as a lifeline to thousands of communities where airlines do not fly, while contributing a fraction of total U.S. air traffic congestion.
