Despite it happening almost 20 years ago, to this day it still unites us all in grief, mourning, and remembrance. It's reported that almost 3,000 people lost their lives that day - including 412 emergency workers of New York City who rose to the call of duty and sacrificed their lives in order to save the lives of complete strangers during one of the most horrific ordeals anybody can possibly go through.
Just as with every year, on September 11th was flooded with hundreds upon thousands of stories about how people from all over the world have honored the thousands of victims who left their homes and families that day not knowing they would never get the chance to return.
They began their climb at 8.46am on September 11th - which is the exact moment the first American Airlines airplane (Flight 11) hit the north tower of the World Trade Center. It was a truly humbling, beautiful moment which I am personally very glad was captured on video. Within the space of 24 hours, the video gained more than 17 million views.
Despite only hearing about this particular story this week, it's not the first time firefighters have paid tribute to their fallen brother. Jason Harding, a public safety officer who works as a policeman, a fireman and a paramedic was pictured donning his firefighter uniform at a gym in Tennesse using the steps machine.
The image was uploaded to Facebook by Lezlie Bauler, who works on the front desk at the gym, with the caption:
After the post went viral, Harding had this to say;
What a truly beautiful sentiment.
