102 Minutes

At 8:44 a.m. on September 11, 2001, the doors closed on the last elevator ever to leave Windows on the World. Inside were Liz Thompson and Geoffrey Wharton, hurrying down from breakfast. On the 88th floor below, Frank and Nicole De Martini had just finished their coffee after dropping their kids at a new school. Receptionist Dianne DeFontes had already been at her desk on the 89th floor for an hour, eating yogurt in the quiet before the day began. Upstairs, Neil Levin, the new executive director of the Port Authority, was having breakfast with an unidentified guest. Investigator Richard Tierney stopped at Levin's table on his way out, wondering who his boss was meeting. Two minutes later, at 8:46 a.m., American Airlines Flight 11 sliced through the north tower, cutting through seven floors and destroying all three escape staircases.

This is where 102 Minutes begins—not as a history of terrorism or geopolitics, but as a minute-by-minute account of what happened inside the World Trade Center towers on that morning. Journalists Jim Dwyer and Kevin Flynn reconstruct the 102 minutes between the first plane's impact and the north tower's collapse, weaving together the stories of the 14,154 people who worked in the towers—about 64 per floor—and the emergency workers who rushed toward them.

The first problem was simple confusion. Most people inside thought a bomb had exploded, not a plane. In the south tower, workers received wildly different instructions depending on which Port Authority officer answered the phone. Some were told to evacuate; others were told the trouble was only in Tower One and to stay put. At Mizuho/Fuji Bank, which had offices on every floor between 78 and 93, employees followed their training and evacuated immediately—only to be told by a guard in the lobby that the problem was in the other building. They returned to work. Fifteen minutes later, United Airlines Flight 175 smashed into the south tower.

The book's central argument emerges from the wreckage: the tragedy was not just an act of terror but a structural and regulatory failure. The World Trade Center towers were built under a 1968 New York City building code that had dramatically reduced safety requirements. Real estate industry advocates had claimed new technologies made old requirements obsolete. The changes allowed for 2% more rentable space per floor—amounting to $1.8 million more per year—but they also reduced the number of required stairwells and fireproofing standards. Columns that once had to withstand fire for four hours now only needed three; floors dropped from three hours to two. The 1938 code would have required six stairwells per tower. The towers had three. Fireproofing tests for the bar joists were never actually conducted.

The authors draw a direct line to the Titanic: both the ship and the towers were considered indestructible, and both had inadequate escape routes. The Titanic's sinking led to massive reforms in flying safety. The World Trade Center's 1993 bombing should have led to reforms in high-rise evacuation and interagency communication. It didn't.

What makes the book devastating is how it shows that hundreds of lives could have been saved. In the south tower, Stairway A remained passable after the second plane hit. But that information never reached fire commanders, 911 dispatchers, or broadcasters. Workers from agencies on upper floors who made their way down turned back, believing all stairs were blocked. Like the half-empty lifeboats on the Titanic, Stairway A remained little used.

Meanwhile, the communication breakdown between New York's fire and police departments was catastrophic. They had not conducted a joint drill since 1982. Firefighters carried the same Motorola Saber radios as in 1993, while newer equipment sat unused. Police helicopters had a clear view of the damage from 8:52 a.m., but no firefighter was aboard to relay the information. When police helicopters radioed about the possibility of collapse almost an hour before it happened, firefighters were cut off from that information.

Yet within this failure, there were acts of extraordinary heroism. Frank De Martini, a Port Authority construction manager, grabbed a crowbar and hardhat and, with three colleagues, began prying open doors, tearing apart elevator shafts, and guiding people to an accessible stairway. They worked on floors 90, 89, 88, 86, and 78, saving at least seventy lives. They found Elaine Duch wandering the 88th floor, dazed and charred, her clothes nearly burnt off after a fireball of fuel blew through the elevator shaft. They helped Raffaele Cava, an elderly man who always wore a hat. Only when ordinary people like De Martini took action could others go free.

The second plane's impact at 9:02 a.m. created a different kind of horror in the south tower. People with broken bones, severed limbs, and burned faces filled the sky lobby on the 78th floor. Mary Jos woke up with her back burning and found herself moving over the remains of people who had been standing near her. Judy Wein had several fractured ribs and a broken arm but could move. Bits of stone and cement lodged into Ed Nicholls' abdomen. Many Mizuho/Fuji employees who had returned to work perished.

The book's most damning insight is what happened inside the north tower during its final minutes. Firefighters believed the building could withstand the fire for at least two hours, based on the promised fireproofing. Police Lieutenant Warren Smith observed firefighters refusing to leave their posts and thought: "The 1993 bombing had shown them it could stand up. It was the Titanic mentality." Police helicopters reported the north tower was glowing red and buckling at 10:19 a.m., but firefighters never received evacuation orders. The building engineers had warned of imminent collapse between 9:45 and 9:50, but the message never reached the men inside.

The north tower collapsed at 10:28 a.m.—exactly 102 minutes after Flight 11 struck. The south tower had fallen twenty-nine minutes earlier, releasing 278 megawatt hours of energy—enough to power all homes in Atlanta, Oakland, or Miami for one hour. The collapse registered on a seismograph in Lisbon, New Hampshire, 265 miles away.

In the aftermath, the authors point to a painful truth: true fireproofing tests were never done until 2004, and they showed the fireproofing was simply not enough. The 1968 code changes that prioritized profit over safety had created a building that looked indestructible but was vulnerable in ways no one understood. The interagency rivalries and communication failures that had persisted since the 1993 bombing cost hundreds of firefighters their lives.

But 102 Minutes is not just an indictment. It is a memorial. It names the people who called their mothers from the top floors, who sang Hebrew hymns on the 97th floor after phoning their wives, who refused to leave their paralyzed friends behind. It follows paramedic Chuck Sereika, who missed work that day and showed up late, then walked home alone through the dust that had been the World Trade Center.

The book leaves you with an uncomfortable question: how many of the lessons of 9/11 have we actually learned? The same patterns—overconfidence in infrastructure, communication breakdowns between agencies, profit prioritized over safety—were present in the 1993 bombing and repeated on September 11. The tragedy itself should have been enough to force change. But as the authors show, the indifference to the lessons of history is hardly limited to municipal government. It is a human failing, one that continues to shape how we build, how we prepare, and how we respond when the unthinkable happens.
