your thoughts today 16 years later? >> well, i was actually a seal instructor on 9/11. and i saw when the plane hit, like many americans, that america is going to change and we have changed. and that you are right, today, the vice president is in shanksville. we're visiting the flight 93 national monument. and i can tell you they are heroes. this is an example of america sticking together. you know, and likely the actions of the passengers and crew of flight 93 prevented, you know, probably a strike on the capitol. we had a joint session with congress at the time. they are heroes. and this monument, if you have not seen it, you know, drive out and take a look at it it's magnificently designed and magnificently done. an example of public private partnerships. national system working together to commemorate american heroes.
