SenesTech was honored to be recognized as the largest participating team at Flagstaff’s 9/11 Tower Challenge, an event created to honor our fallen first responders. Vowing “Never to Forget” participants of the 9/11 Tower Challenge walk, climb, or run stairs consisting of 2,071 steps, representative of the 110 flights inside the Twin Towers.

During the challenge, civilians climb alongside active firefighters, police, bomb squad, and military service members, not only to remember those who made the ultimate sacrifice that day, but also to show respect for those willing to do so today.

Battalion Chief of Highlands Fire District, Mike Greenwalt, is one of these responders and reflected on that tragic day:

“I was a firefighter on a military base on September 11, 2001. Up until that time, I thought I knew what selfless service meant. But after the events that happened on that day, I had a much better understanding of what I signed up for. 18 years later, this day is a reaffirmation of what I owe to the country, my community, and my fellow firefighters.”

Lining the steps of Northern Arizona University’s Walkup Skydome were photographs of those who lost their lives in service to their country and fellow citizens that day. One of SenesTech’s many participants, Sharon Dinges, Product Marketing Manager, reflected on the challenge, remarking, “It was quite sobering to climb the steps past the photos of the fallen First Responders. The 2071 step climb – which I was unable to complete this year – was nothing compared to climb of the First Responders on 9/11/2001.”

Of course, she was quick to point out that the SenesTech team took up the challenge in the comfort of the NAU football stadium. “The Twin Tower First Responders were climbing up and into burning and crumbling high-rise buildings – with full gear. Knowing they were unlikely to leave the buildings once they entered.”

The 911 Tower Challenge Foundation identifies one of its goals as reconnecting participants “to the kindness, strength and bravery exhibited on that dark day.”

Mission accomplished.

“I was moved by the resilience of the human spirit and the solidarity of community,” Sharon said.
