Six years after Oklahoma suffered through its own terrorist attack - the bombing of the Alfred P. Murrah Federal Building in 1995 - the feelings of solidarity with the people impacted by the events of September 11, 2001 were particularly keen here.
And Oklahoma stepped up to help with aid, volunteers, and peer support for families and loved ones of those lost.
20 years later, the state continues to hold events of commemoration, like the Edmond Fire Department's 110-story stair climb, and the 9/11 Heroes Run, which takes place next weekend.
Some of the state's leaders are weighing in with their thoughts on the anniversary.
Gov. Kevin Stitt tweeted that he spent part of Saturday morning in Tulsa meeting with firefighters and first responders to "remember the heroism and bravery of those who responded to the 9/11 attacks..."
U.S. Senator Jim Inhofe released a statement Friday.
"As we remember and honor the lives lost twenty years ago ... I wanted to remember the many brave men and women who have lost their lives fighting for our country since that fateful day," Inhofe said.
And Oklahoma House Speaker Charles McCall said in a press release the "pain of the Sept. 11, 2001 attacks still burns after 20 years. On this anniversary and every day after it, the best tribute to those we lost is committing ourselves to preserving the American strength, freedom and liberty the terrorists tried - and failed - to destroy that day."
