9/11 Museum CEO reflects on lasting impact of terror attacks as America marks 250th birthday

As America marks its 250th anniversary, 9/11 Memorial and Museum President and CEO Elizabeth L. Hillman said this year's milestone coincides with the 25th anniversary of the Sept. 11, 2001, terrorist attacks, highlighting the nation's past and its resilience.

"This year, America's 250th birthday coincides with the 25th anniversary of 9/11, which means that what's happening at our site is very much connected to the history of the country and to the recognition of this important milestone," Hillman told Fox News Digital.

"9/11 is an important part of our nation's history, but especially now as the nation turns 250."

Nearly 3,000 people were killed in the terrorist attacks when hijacked planes struck the World Trade Center, the Pentagon and a field near Shanksville, Pennsylvania.

Hillman said it is more important than ever for future generations to learn about the Sept. 11, 2001, terrorist attacks to understand how they helped shape the nation and "where we are today."

"Now, 25 years have passed since that date, so if we don't elevate 9/11 in the eyes of the 100 million Americans who were born since or were too young to remember 9/11 when it happened, we'll lose the opportunity for them to understand what happened on that day and how the world came to heal, how the nation came together, and how this city and the other sites, the Pentagon and Shanksville, Pennsylvania, worked to recover afterward," she said.

Hillman said the nation's recovery after 9/11 shows that even after a devastating tragedy, people can come together, heal and rebuild.

"I think everyone's hungry for evidence that we can survive things that are difficult," she said. "There's nothing like 9/11 to help people realize, given how the nation has recovered since, that it is possible to persevere, to heal, to recover, even in the face of really unfathomable loss, and that's what 9/11 has the chance to teach us."

Reflecting on the museum's role, Hillman said the Sept. 11, 2001, terrorist attacks affected not only New York City but the entire country, calling the museum "a testament to the resilience of the city" and to "the perseverance that enabled us to actually rebuild."

"At the center of the rebuilt World Trade Center is a monument to the people who were killed that day and a testimony, really, to what we can do when we come together after that kind of catastrophe," she said.

This year, the museum opened "Our Flag Was Still There," an exhibition featuring flags, artifacts and photographs that tell stories of resilience from first responders, veterans and Americans who lived through 9/11. The exhibit includes the Ground Zero flag raised by FDNY firefighters, the flag draped over the Pentagon by soldiers and firefighters, a flag raised over the last column of the South Tower, and one carried during the mission that killed Usama bin Laden.

"It reveals how important the flag was in the healing and the coming together that happened after 9/11," Hillman said.

Hillman said commemorating 9/11 is especially important at a time when "many things seem to be splitting us apart."

"The opportunity to bring people together around a symbol like the flag and around a symbol like the rebuilding of the World Trade Center after 9/11, it's a great opportunity, especially right now," she said.

On July 4, Hillman said the museum will place an American flag at each victim's name on the memorial, "to recognize how important the flag was as a symbol of the country on its birthday, but also of the recovery from 9/11 that happened and continues to happen now as we remember that day at this site."

Looking ahead to fall, Hillman said the museum will also start offering free admission to veterans whose "willingness to serve after 9/11" helped rebuild the World Trade Center and unite the nation.

"If there's one message that we feel we can elevate now that we couldn't do 25 years ago because we didn't know enough about what would happen afterward, it's that so many people were inspired to serve their country, serving in the military," she said.
