Monday marked the 16th anniversary of the terror attacks in New York City and Washington, D.C., that killed almost 3,000 people, including people in the World Trade Center and the Pentagon, first responders and all passengers in the four hijacked planes. 

On Sunday, volunteers with the Civic Service Institute at Northern Arizona University placed flags in the ground at Flagstaff City Hall in memory of the people killed that day.

On Friday at the Skydome, members of NAU’s Army and Air Force ROTC joined Flagstaff first responders for the 9/11 Tower Challenge. The challenge is a statewide fundraiser that encourages participants to climb 110 floors or 2,071 steps, the same number as in the World Trade Center.

“It is a day to honor, reflect and never forget,” President Rita Cheng said.
