9/11 history on display at Hall of Flame Museum in Phoenix ABC15 and last updated 2021-05-02 20:01:18-04 PHOENIX â It's been nearly 20 years since the terror attacks on September 11, 2001. First responders say that moment in history deserves to be honored more than once a year, which is why a ceremony was held at the Hall of Flame Museum in Phoenix on Sunday. The ceremony included stories from firefighters who were there that day and a walk around the museum in honor of those who lost their lives. For the past few months, a replica of the World Trade Center Plaza created by a teenager in the Netherlands has sat in the museum. The non-profit Honor 365 is taking it on a tour around the country, and it is now headed to New Mexico.
