The National September 11 Memorial & Museum's president and CEO, Beth Hillman, reflects on the enduring power of the American flag 25 years after 9/11. The flag, which represents a shared mission, identity, and responsibility to preserve freedom, was used as a symbol of resilience during the country's darkest hour following the terrorist attacks. Hillman believes that the flag represents a larger purpose than individualism and a powerful collective memory. The museum is beginning its 25th anniversary programming with a special installation entitled "Our Flag Was Still There," which will open to the public on March 18, 2026. The installation will feature historic flags from key moments over the past quarter century, including those flown during the attacks on the Twin Towers and the Pentagon, and the rescue and recovery process.
