Several ceremonies on the Seacoast will mark the 21st anniversary of the terrorist attacks on the World Trade Center, the Pentagon, and a plane that crashed in a Pennsylvania field.

Members of the Portsmouth Police and Fire Departments will lead a ceremony on Sunday morning at the 9/11 steel artifact memorial at police headquarters starting at 8:46 a.m., the time American Airlines Flight 11 crashed into the North Tower of the World Trade Center in New York. The plane was piloted by Portsmouth resident Tom McGuiness.

Attendees are invited to bring a flower or bouquet to lay at the foot of the artifact.

The Knights of Columbus will hold a Blue Mass at St. Joseph's Church in Dover on the 11th at 5 p.m., to recognize 72 law enforcement officers, 343 firefighters, and 10 emergency medical workers who died in the attack.

Gov. Chris Sununu has ordered flags on all public buildings and grounds to fly at half staff on Sunday.

“As we observe the twenty-first anniversary of the solemn attacks on September 11, we remember the victims tragically lost, the first responders who selflessly rushed into the burning towers without hesitation, and the brave men and women who have fought to protect our country in the years since,” Sununu said in a statement. “I encourage all New Hampshire residents to pause and reflect on the actions of our nation’s first responders and veterans who heroically put their lives on the line to save others and protect our freedoms.”

8 Places the 9/11 Terrorists Were Spotted in Maine

On the anniversary of 9/11, we remember the chilling fact that two of the terrorists came to Maine. In a press release from October 2001, the FBI detailed the times and locations of Mohammed Atta and Abdulaziz al-Omari on both September 10 and 11, 2001, in Maine before their flight left Portland for Boston.
