As the 22nd anniversary of 9/11 looms, the Canadian Volunteer Fire Department has again announced plans for its fourth annual tribute to the firefighters who responded to the September 11, 2001, attack on the World Trade Center in New York City.

In solemn remembrance of both the tragedy and heroism of that day, Canadian’s volunteer firefighters will hold “A Climb to Remember” at Wildcat Stadium on Saturday morning, September 9. In what has become an honored tradition, firefighters will climb the stadium steps—many of them in full gear—as a tribute to the NYC firefighters who climbed 2,071 steps, lugging 60 pounds of equipment, in a valiant attempt to evacuate the occupants of the World Trade Center towers.

Canadian’s firefighters will assemble at 8 am Saturday at the stadium. They invite the public to join them for all or part of the stair climb, and will even have some extra bunker gear with them in case anyone else wants to try it on. Coffee and donuts will be available for all who wish to join them in the memorial event.

Those who choose to go the full distance will climb 54 flights on the stadium’s home side. That is 2,100 steps, in all.

On Sept. 11, 2001, at 8:46 am, an American Airlines 767 loaded with jet fuel crashed into the north tower of the 110-story building. The impact instantly killed hundreds of people and trapped hundreds more above the 80th floor, where flames burned through a gaping hole.

Eighteen minutes later, a second Boeing 767 appeared in the sky, turned toward the World Trade Center, and struck the skyscraper’s south tower near the 60th floor, leaving no doubt that either collision was accidental.

An hour later, a Boeing 767 crashed into the west side of the Pentagon, creating an inferno that killed 125 military personnel and civilians, as well as the 64 passengers onboard. In another 15 minutes, the south tower of the World Trade Center collapsed, followed within 30 minutes by the collapse of the north tower.

As passengers onboard United Flight 93—which had just taken off from Newark Liberty International—listened to news of those events, their airplane was hijacked by four men. Knowing with grave certainty what was ahead, the passengers and flight attendants resisted the terrorists. Their plane crashed in a field in western Pennsylvania, killing all 44 aboard.

Altogether, 2,977 people were killed in the 9/11 attacks, as well as the 19 hijackers. More than 6,000 others were injured. Most of those who died were civilians, except for 343 firefighters and paramedics, and 71 law enforcement officers.

None will be forgotten.
