Two Florida students took part in a memorial stair climb on Tuesday, Sept. 10, in honor of the firefighters who lost their lives at the World Trade Center on 9/11. They walked up more than 100 flights of stairs while reciting the names of the firefighters.

The two students are Samuel Maritn and Devin Turner, members of Bartow High School’s Medical and Fire Academy.

The Polk County School said in a Facebook post that the boys were dressed in full firefighting gear.

“While resting between flights, they recited the names of the 343 New York City firefighters killed in the World Trade Center attacks,” the post wrote.

“We go through the history of the fire service, and 9/11 is a focal point in that history. We keep this day at the forefront when talking about loss,” said Kozette Hubbard, a BHS Medical and Fire Academy instructor. “I am very proud of these young men and the fact that they did this on their own. We push our cadets to be forward thinkers and always remember service to others before self … this is just a small snapshot of what the cadets are capable of.”

On the 18th anniversary of the Sept. 11, 2001, the event Memorial Stair Climb was held around the country by the National Fallen Firefighters Foundation, in which firefighters climb 110 flights staircase, just like the World Trade Center towers.
