Hundreds of firefighters from Nashville and six other states gathered in downtown Nashville Sunday to remember the men and women lost in the September 11 terrorist attacks.
Dressed in full gear, firefighters began climbing the stairs of the Tennessee Tower at 9 a.m., the exact time the first World Trade Center building was hit in 2001.
Hundreds of men climbed 112 stories to remember 343 fallen heroes.
Nashville Fire Captain Trey Nelms has been climbing since the event was created in 2010.
"Knowing that they didn't get to finish that day but you finished for them," Nelms said. "Being able to ring that bell, it's a big deal."
Each firefighter read a name of the fallen and rung a bell to symbolize the lost after finishing their climb.
Firefighters in groups of seven climbed the 28 stories four times on Sunday, some even carrying coils of fire hose.
"Like I said, you just trudge on through because you think about what those guys were doing that day," Nelms said. "They probably knew that they had a chance of not coming back, but they pressed on. That's what we do, press on for them."
This year's climb sold out three hours after registration opened July 2.
