On the last day of the recovery at Ground Zero, ten people carried an empty stretcher up out of the pit. There was nobody on it. Just a folded American flag. They carried it for the two thousand who were never found. The recovery operation at the World Trade Center site ran for eight and a half months. September 11, 2001 to May 30, 2002. Two hundred and sixty-one days. Nearly two million tons of debris removed, by hand and by crane, and sifted, and searched. Near the end, one thing was still standing. A steel column. Thirty-six feet tall, fifty-some tons. Column 1001B, one of the 47 columns that had held up the core of the South Tower. When everything else came down, this one stayed upright in the wreckage, half-buried, and the workers found it as they dug. They started writing on it. Firefighters spray-painted the numbers of their companies. Squad 41. Ladder 3. Engine 54. The units that had lost everyone. Police wrote precinct numbers. Ironworkers wrote their local. Someone taped up a missing poster, then someone else, then hundreds. Rosaries were hung. Photographs. Mass cards. A Marine wrote a name and a date. Somebody wrote the numbers 343, and 23, and 37, for the firefighters, the police, and the Port Authority officers who had died. By spring the column was covered top to bottom in the handwriting of the people who had spent eight months on their knees in that hole. They called it the Last Column. On the night of May 28, 2002, there was a ceremony nobody outside the site was invited to. It was for the workers only. The ironworkers cut the column loose from the bedrock with torches. They wrapped it in black cloth. They laid an American flag over it. They lowered it onto a flatbed truck. Bagpipers played Amazing Grace. Two days later, on the morning of May 30, the city held the public ceremony. There were no speeches. That had been decided in advance. No politician spoke. No official read a statement. Not one word was said into a microphone except the order calling the honor guard to attention. At 10:29 a.m., the minute the North Tower had fallen, a fire department bell rang. Five strokes. Four times. Five-five-five-five. The signal the FDNY has used for more than a century to tell the department that a firefighter has died. Then an honor guard formed at the bottom of the pit. FDNY. NYPD. Port Authority Police. EMS. State troopers. National Guard. Court officers. Correction officers. Construction workers. Volunteers. Family members. Ten of them stepped forward and lifted a stretcher. The stretcher was empty. Draped across it was a folded American flag. That was all. No body. No remains. A flag on a stretcher, for the roughly two thousand people who had been in those buildings on September 11 and had never been found. Not a bone. Not a tooth. Not a ring. Nothing to bury. The flag was for them. The ten carried it slowly up the five-hundred-foot ramp that led out of the pit. Thousands of people lined the ramp. Widows. Children. Firefighters in dress blues. Nobody spoke. Some of them held photographs. Some of them saluted. The only sound was boots on the ramp and the wind, which still carried, eight months later, a faint trace of the smell that had hung over lower Manhattan since September. At the top of the ramp, an ambulance was waiting with its doors open. They slid the empty stretcher inside. They closed the doors. That was the moment the recovery ended. Then the pipes and drums began. The flatbed truck carrying the Last Column, shrouded in black, draped in the flag, covered in the handwriting of the men who had found it, rolled slowly up the ramp behind the ambulance. Police helicopters passed overhead in formation. Buglers played Taps. The pipers played America the Beautiful. And the truck drove out onto the West Side Highway, and turned north, and the honor guard formed a line across the top of the ramp behind it, and closed the site. A battalion chief who had been inside the North Tower when it was hit said the only thing anyone said that day that was worth printing. It's over. But it will never be forgotten. The Last Column is in the 9/11 Memorial Museum now. You can stand next to it. You can read the spray paint. Squad 41. Ladder 3. The missing posters are preserved under glass, exactly where they were taped. The stretcher is not in a museum. It was empty. There was nothing to keep. For eight and a half months, ninety thousand people dug through a mountain looking for their dead. On the last day, they carried out the ones they could not find. 🇺🇸
