But again, we, I think, over the years have set the example for a lot of nations that may not have had the same values, the same type of coming out of the same culture that we as Americans have and enjoy. But we can be an example, a role model to them.

I feel very confident that Americans flying in the air are safe, and that only under the most dire of circumstances would our pilots even request permission to do that.

But, the other thing is, is that I feel very confident in the individual pilots. They are tremendous individuals. They are individuals that have sworn to protect and defend our very citizens. That is why we served...

We came back right over the World Trade Center, and could see, even from that altitude the devastation, the smoke that was coming up. It was obvious it was going to be horrible.

But it's been a great, humbling - and I've been very honored to have the opportunity to serve and to lead and to be the representative of our soldiers, sailors, airmen and Marines who are in Washington. And it's been the greatest honor of my life.

I always concentrated on doing the very best that I could in the job and the duties that I was assigned.

I, first of all, felt a great sense of loss, a sense of condolence for the friends that I had that were killed in that, for the loved ones.
