Long Shadow

After both towers of the World Trade Center were hit on September 11, 2001, first responders coordinated the largest emergency response in New York City’s history. But their heroism at Ground Zero was hampered by institutional bureaucracy and ultimately undone by decisions made decades earlier, when the Twin Towers were built.

So why did these iconic structures and architectural marvels fall so fast? Could more people h...

With the Capitol under attack, the President on Air Force One, and the Defense Secretary missing, Vice President Dick Cheney was the most powerful man in the country on the morning of 9/11. From a bunker beneath the White House, he gave fighter pilots flying above the Capitol permission to shoot down hijacked commercial planes.

But did Cheney actually have the authority to issue this order? Did he and President Bush con...

Before 9/11, FBI Special Agent John O’Neill kept setting off alarms about the emerging terrorist organization al-Qaeda and their mysterious leader Osama Bin Laden. As a result of his warnings the FBI knew terrorists were planning a big attack and the CIA even had eyes on two of the eventual hijackers prior to the attacks.

So what went wrong? Why didn’t they capture the hijackers? What more could law enforcement have don...

Immediately after 9/11, investigators began piecing together the plot. In the flight manifests, they discovered a pattern: A team of five terrorists hijacked every plane that day, except for one. United Airlines Flight 93 had only four hijackers. Investigators believed one person was missing from that group.

Who was the 20th hijacker — if there even was one? And is there a 9/11 hijacker still on the loose? 

Fifteen of the 19 hijackers on 9/11 were from Saudi Arabia, which was also the home of al-Qaeda’s leader, Osama Bin Laden. In the days after September 11, dozens of his friends, family members and business associates left the U.S. on secret flights bound for The Kingdom of Saudi Arabia. That has led to questions that four presidents have avoided answering:

What role did the Saudi government play in the attacks? What did...

When we think about 9/11, we often only think of the tremendous loss of life on that day. But what we sometimes forget about are those who made it; the thousands of people who survived the attacks, but have had to carry it with them every day since. 

Firefighter Jay Jonas and Port Authority Police Officer Will Jimeno were in the Twin Towers on September 11 — 100 stories of the World Trade Center fell on top each of them...

The Ruby Ridge raid, the Waco siege at the Branch Davidian compound, the Oklahoma City bombing, the Jan. 6 insurrection… they are all explosive moments in recent U.S. history. But connect the dots between these—and other—seemingly disparate, violent events, and you’ll answer some of the most existential questions facing the U.S. today: How did America get the far right so wrong? What will it take now to get it right?

In LO...

This season host Garrett Graff, in collaboration with The Trace, recounts how a very specific, carefully manufactured fear has driven explosive demand for guns across the U.S. It’s the history of how firearms went from being an ordinary part of rural American life to a menacing element in modern society — and the epidemic of gun violence that’s come with it. How did we get here — how did America get so divided over guns — ...
