Name the murderers, honor the resolve

The 9/11 Commission's timeline fixes the morning to the second, and the seconds matter, because precision is how a free people refuse to let murder dissolve into fog. At 8:46:40, American Airlines Flight 11 struck the North Tower. At 9:03:11, United Airlines Flight 175 struck the South. At 9:37:46, American Airlines Flight 77 struck the Pentagon. At 10:03:11, United Airlines Flight 93 went down in a field near Shanksville, Pennsylvania. The South Tower fell at 9:58:59; the North followed at 10:28. Nineteen men of al-Qaeda seized four airliners that morning and turned them into weapons, and the record of what they did is exact enough to hold them to it.

The chain of responsibility is just as exact. In the spring of 1999, in Kandahar, Usama bin Ladin told Khalid Sheikh Mohammed that al-Qaeda would back his proposal to use commercial airplanes as weapons, and the plot took its internal name: the planes operation. The Commission calls KSM the principal architect of the 9/11 attacks (http://en.wikisource.org/wiki/9/11_Commission_Report/Chapter_5); its executive summary records that by late 1998 or early 1999, Bin Ladin and his advisers had agreed on the idea KSM brought them (https://911commission.gov/report/911Report_Exec.htm). In the field the operation had a commander: Mohamed Atta, chosen as emir, the man who flew Flight 11 into the North Tower. The nineteen were fifteen Saudis, two Emiratis, one Lebanese, one Egyptian. Shortly after 8:24 that morning, trying to address his own cabin, Atta keyed the wrong switch and broadcast to air traffic control instead. The voice, believed to be his, said: "We have some planes. Just stay quiet and you'll be O.K. We are returning to the airport." The opening chapter of the Commission's report takes its title from those words: "We Have Some Planes."

The murder weapons were legal. The FAA's rules that morning allowed knives with blades up to four inches aboard an aircraft, and an aviation security expert later put the consequence plainly: even if screeners had caught the hijackers' blades, they would have handed them right back. By 8:00 a.m., the Commission found, the nineteen had defeated every layer of civil aviation security then in place. What followed was not abstract. Hundreds died on impact; hundreds more, trapped above the strike floors with the stairwells cut, faced fire and smoke and a choice no person should ever be given. At the Pentagon, the plane hit the one section of the building that had finished a years-long renovation, Wedge 1, refitted with blast-resistant windows, steel reinforcement, and Kevlar panels after the Oklahoma City bombing. The hardened structure held for twenty to thirty minutes (https://www.defensemedianetwork.com/stories/rebuilding-the-pentagon/4/), long enough for people to get out; demolition crews later found a message scrawled on a wall inside: "Thank you for the safety windows + reinforcement! All our people escaped!" The renovation manager told reporters the attack "happened to hit an area that we had built so sturdily," and that it could have been much worse anywhere else in the building.

Resolve answered the same morning, at every level. Ben Sliney, the FAA's National Operations Manager, was on his first day in the job. At about 9:25 he imposed a nationwide ground stop, halting departures. After the Pentagon was hit, at 9:42, he ordered every aircraft in American airspace to land at the nearest suitable airport, an order the Commission calls unprecedented. About 4,500 commercial and general-aviation aircraft came down without incident (http://www.bricklin.com/911excerpts.htm). The ones already past the point of no return over the Atlantic went north: Canada's Operation Yellow Ribbon took roughly 238 diverted aircraft at seventeen airports, and Gander, Newfoundland, a town of fewer than 10,000, absorbed 38 planes and some 6,600 strangers in a single morning, nearly doubling its population overnight. And at 9:57, the passengers and crew of Flight 93, who had learned by airphone what the hijackers' blades had already done in New York and Washington, rose and fought for the cockpit. The Commission's verdict on Ziad Jarrah stands as the plainest sentence in the report: he was defeated by the alerted, unarmed passengers of United 93.

The Memorial's accounting is the shape of the loss: 2,753 dead in New York, 184 at the Pentagon, 40 at Shanksville, 2,977 in all; 246 passengers and crew aboard the four planes; the 19 hijackers counted apart. Among the dead were 441 responders, including 343 FDNY firefighters, 37 Port Authority police officers, and 23 NYPD officers. These are not symbols. They are names on bronze parapets, and the parapets are arranged by where each person was and who each person was with, because that is what an open society owes its dead: the truth, kept exact.

Clarity is the duty, and clarity has enemies on two sides. The "inside job" stories contradict the evidence base built by the Commission and by NIST, whose investigators spent years on the collapses, including the 47-story WTC 7, which fell late that afternoon. NIST's 2008 report found the tower's fall was the first known instance of fire causing the total collapse of a tall building (https://phys.org/news/2008-08-nist-wtc-collapse.amp), and its lead investigator stated that video, photographic, and simulation evidence showed "neither explosives nor fuel oil fires played a role." Fantasies about controlled demolition do the murderers' work for them: they move the agency off the nineteen men who actually did it. So does the vaguer habit of dissolving the attacks into a "cycle of violence," as though nineteen named men with named leaders and a named ideology were a weather event. Al-Qaeda named itself. Bin Ladin approved the operation. KSM designed it. Atta led it in the field. Blurring that into abstraction is not compassion; it is erasure.

Flight 93 is the answer to the erasure. Ordinary people, told the truth over telephones, understood in minutes what the hijackers intended and refused to be cargo. They refused the knife, the same legal blades the system had permitted, and they paid the full price at 10:03:11 in a Pennsylvania field. That resolve is not a metaphor. It is a civic duty, demonstrated once under the worst conditions imaginable: know what is happening, name who is doing it, and act. Never forget what happened. Never forget who did it.
