Thirteen years ago, on September 11, 2001, our nation was attacked. We pause today to reflect -- to remember and honor those we've lost.

Americans are a resilient people, and that resilience was on display at the ceremony in lower Manhattan that marked the 9/11 attacks 13 years ago.

Names were read at the plaza, almost 3,000 of them, and while the tone was somber, some family members also took that time to look forward...

(Family Member) " Even though I really didn't know you, you will always be family in my heart and I will always love you. And in your honor, I have decided to serve our country with the United States Marine Corps."

People of all ages gathered to pay tribute to those who died, at times, taking on the feel of a reunion. A plaza of people who will forever share the bond of losing a loved on 9/11.

Sept 11 Pennsylvania

And 13 years after 9/11, they remembered on the field where a plane crashed in Pennsylvania.

FOX News Radio's Dave Anthony reports:

It's the flight where passengers fought back and battled the terrorist hijackers until United 93 crashed.

The ceremony 13 years later included tolling bells right when it went down on 9/11 at 10:03 am. Then the reading of the names of the 40 passengers and crew members killed.

A Congressional Gold Medal was presented honoring the victims posthumously and former House Speaker Dennis Hastert donated to the Flight 93 National Memorial the flag flying atop the Capitol that day smudged by smoke from the fire at the Pentagon.
