John Abruzzo’s story is not only about a remarkable escape.

It is about who an evacuation plan imagines.

Buildings are often described through height, steel, elevators, offices, and occupancy. Emergency instructions can sound equally impersonal: use the stairs, do not use the elevators, proceed to the nearest exit.

Those instructions are written in verbs that presume bodies able to perform them. Abruzzo’s experience forced planners and later museum visitors to consider the people for whom “use the stairs” is not an independent action.

For someone who cannot walk down dozens of flights, those instructions are incomplete.

Abruzzo survived the 1993 World Trade Center bombing, but the six-hour evacuation exposed how poorly the building’s emergency system served people with limited mobility. The evacuation chair installed afterward did not erase that vulnerability. It gave coworkers a practical tool for responding to it.

On September 11, the tool worked because people used it together.

Mike Fabiano remembered Abruzzo. Someone located the chair. Ten coworkers remained. One scouted ahead. Others rotated through physically demanding positions. The group changed stairways when smoke made the route dangerous. They refused to leave Abruzzo at a temporary aid point. Firefighters helped them through the damaged lobby and later carried the chair into Stuyvesant High School.

The survival belongs to all of those actions.

It also belongs to time.

Flight 11 struck the North Tower at 8:46 a.m. The building collapsed at 10:28 a.m. Abruzzo and his coworkers escaped within that 102-minute span.

The outcome was not guaranteed by the chair’s presence. Equipment can be missing, inaccessible, poorly maintained, or unfamiliar to the people expected to use it. Plans can fail if no one knows whom they include.

The North Tower story therefore resists a simple hero narrative. Courage mattered, but courage operated through preparation: a device purchased after an earlier failure, coworkers who knew where it was, and a group willing to coordinate under pressure.

The 69-floor descent also warns against treating disability evacuation as a last-minute act of generosity. The chair existed because an earlier emergency had already shown the need. Effective inclusion had to begin before smoke entered the building.

The available evidence suggests that the most important legacy of Abruzzo’s escape is the combination of design and relationship. The chair made the route physically possible. The coworkers made the route humanly possible.

That conclusion is an inference drawn from the documented sequence, not a claim about what any one rescuer privately believed.

The words they did preserve are simpler.

At the aid point, they said John was with them.

Years later, Curci said the group shared a bond that did not need to be explained.

Abruzzo said thanks was not enough.

The chair now gives those words a physical form.

Visitors can look at it and ask practical questions. How would a person with a disability leave this office? Where is the equipment? Who is trained? Who checks the route? Who stays?

The questions are not rhetorical. They can be asked in any school, hospital, office tower, apartment building, or public venue where stairs become the only usable exit during an emergency.

Those questions extend far beyond one building and one day.

They are part of the continuing history of 9/11 because the attacks revealed not only extraordinary courage but also the consequences of decisions made long before an emergency begins.

John Abruzzo lost his customized wheelchair and his van. He inhaled smoke and was taken to a hospital. Yet he survived his second attack on the World Trade Center.

The ten coworkers survived with him.

The object that carried him survived too.

Under museum lights, the EVAC+CHAIR appears still and almost fragile. It does not show the crowds, the tight turns, the smoke near the 40th floor, the firefighters climbing upward, the broken glass in the lobby, or the cloud racing along West Street.

Those details live in the record around it.

The record has limits, and respecting them is part of remembering honestly. It cannot provide every sentence spoken on the stairs or every private thought. It provides something stronger: named witnesses, a recorded interview, contemporary reporting, a museum accession, and the surviving chair.

The chair’s power comes from what it does not have to exaggerate.

It came down 69 floors.

It carried a man out of the North Tower.

And ten people carried it all the way.
