On a Thursday in early May, a flatbed truck rolled into the rolling green countryside of Somerset County, Pennsylvania, carrying something that did not belong to this quiet corner of the state. It was a 16,000-pound beam of steel, twisted and scarred, pulled from the wreckage of the South Tower of the World Trade Center. For a day, it sat at the Flight 93 National Memorial in Shanksville, where the ground itself holds the memory of another September morning. The beam was the centerpiece of Steel Across America, a coast-to-coast memorial tour organized by the Tunnel to Towers Foundation to mark the 25th anniversary of the September 11 attacks, and its stop in Shanksville was, by the foundation's own reckoning, one of the most important of the entire journey.
The tour began just days earlier, on May 2, 2026, in Lower Manhattan, steps from where the Twin Towers once stood. Over the following four months it would travel more than 10,500 miles, making more than 35 stops across 21 states, before returning to New York City on September 11, 2026, the 25th anniversary of the attacks. The beam itself is a relic of staggering weight and meaning: recovered by the thousands of first responders who rushed to Ground Zero in the days after the towers fell, it has been held by the foundation for nearly a quarter of a century. Frank Siller, the foundation's chairman and CEO, has said he kept the steel for roughly 20 years before deciding exactly what to do with it. "I've been holding on to it for 20, almost 25 years, and now I know exactly what we're going to do with it," he said. "We have it all going around America, and that has the stories of Shanksville, and has the story of the Pentagon, and it has a story of, of course, the Twin Towers that went down."
The story of the foundation, and of the tour, begins with a single firefighter. Stephen Siller was the youngest of seven children, an FDNY firefighter assigned to Squad 1 in Brooklyn. On the morning of September 11, 2001, he had just finished his night shift and was on his way to play golf with his brothers when he heard over his scanner that a plane had struck the North Tower. He turned his truck around, returned to his firehouse for his gear, and drove toward the Brooklyn Battery Tunnel. When he arrived, the tunnel had already been closed for security. Determined to carry out his duty, Stephen strapped 60 pounds of fire gear onto his back and ran on foot through the tunnel toward the Twin Towers, where he gave his life saving others. His body was never recovered. "My father's body was never recovered," his son, Stephen Siller Jr., said at the Shanksville stop. "Who he was is ingrained in that steel."
In the aftermath, Stephen's brother Frank proposed starting a foundation to honor what Stephen and so many others did that day. The family agreed, and the Tunnel to Towers Foundation was born in December 2001, named for the run Stephen made through the tunnel to the towers. Over the past quarter century it has grown into a major national charity, providing mortgage-free homes to Gold Star and fallen first responder families with young children, building specially adapted smart homes for catastrophically injured veterans and first responders, and funding scholarships for the children of the families it serves. Steel Across America is the foundation's signature event for the 25th anniversary, an effort to bring the sacred artifact to communities that might otherwise never see it. "This tour is about ensuring that every generation can remember, and truly understand, what happened 25 years ago," Frank Siller said at the launch. "No one, regardless of their age or where they live, should ever forget what happened here or the bravery that was shown by so many heroes."
The Shanksville stop, the fourth of the tour, carried a particular resonance. It was here, in a field in Stonycreek Township, that United Airlines Flight 93 crashed on the morning of September 11, 2001, after its 40 passengers and crew members voted to fight back against their hijackers. Their actions thwarted the attack on the U.S. Capitol, saving countless lives. "This is where 40 heroes lost their lives saving countless others," Stephen Siller Jr. said. "This is one of the most important stops we'll make along the way." Flight 93 National Memorial Superintendent Stephen Clark echoed the sentiment, calling what the passengers and crew did "nothing short of extraordinary, without a doubt saving countless lives, having not had their hijacked airplane reach their intended target, which was the U.S. Capitol."
The beam was welcomed at the memorial by a piece of local history: the first fire engine to respond to the Flight 93 crash site in 2001. The Shanksville Volunteer Fire Department's engine, which had been in service since 1993, rolled out of the station that morning with four firefighters aboard and was the first apparatus on the scene. Twenty-five years later, it stood beside the steel from New York, two relics of the same day meeting across the miles. "It's moving," Shanksville Fire Chief Chris Meyer said. "There's no other apparatus in the county that was here that day. It's a feeling that never leaves you. It's a memorial. It's sacred." The engine's presence was a reminder of how small the world of that day was: a volunteer fire department in a Pennsylvania borough of a few hundred people, responding to a crash in a field, and a firefighter in Brooklyn running through a tunnel, both caught in the same unfolding catastrophe.
The connection between the two places was made personal by retired FDNY firefighter Joseph Lapointe, who stood with the beam in Shanksville. Lapointe was off duty on September 11, 2001, working a side job when a delivery man came in and told him a plane had hit the World Trade Center. "It's just powerful," he said. "It's the same when you go to the 9/11 memorial, the Pentagon — you get the visual." Though he and Meyer were thousands of miles apart on that day, the beam bound their stories together. "This piece of steel going around is a piece of here," Frank Siller added. "Even though it's from the South Tower, that's the same story that is here."
For the people who came to the memorial that day, the beam was more than an artifact; it was something to be touched. Foundation officials said visitors were often overcome with emotion when they saw the steel, but it was when they were invited to place a hand on it that the connection truly came, offering a prayer or a moment of silence. The tour also carried a generational mission. Superintendent Clark noted that at least 100,000 Americans have been born since 9/11, and events like this are one way the memorial works to educate the next generation about that day. Seventeen-year-old Lillyann Strait, the American Legion County Fair Queen, was at the stop raising money for the foundation. "It's really important to involve the younger generation in issues involving America even before we were born, because it's important to keep that passion for our country alive," she said.
The beam left Somerset County that Thursday, but it took the memories of Flight 93 with it. "There are so many guys who never got the chance to go back to their families, just like my father," Stephen Siller Jr. said. "They're embedded in that steel. That needs to be remembered." The tour pressed on, heading to Georgia and Florida and then across the country, visiting landmark locations, town squares, major sporting events, and the White House before its final return to Ground Zero on September 11, 2026. In the months that followed, the Shanksville fire department announced it would retire the engine that had responded to Flight 93, ending a 33-year career that had made it the department's first-out apparatus for emergency calls. The engine that met the steel in May, and the steel itself, will each carry their own piece of that day forward — one into retirement, the other back to New York, where the journey began and where, on the 25th anniversary, it will end.
