On September 11, 2001, nineteen men hijacked four commercial airliners and crashed them into the World Trade Center, the Pentagon, and a field in Pennsylvania. It was the deadliest terrorist attack on American soil, killing nearly 3,000 people. But the attack did not emerge from nowhere. It was the culmination of decades of geopolitical maneuvering, a failed intelligence apparatus, and the rise of a radical ideology that had been quietly building since the Soviet-Afghan War. This episode of Historically High traces the long, tangled road to 9/11, from the Cold War to the final moments before the planes took off.

The Making of Osama bin Laden and Al-Qaeda

Osama bin Laden was born in 1957 into immense wealth. His father, Mohammed bin Laden, had built a construction empire in Saudi Arabia by winning the trust of the royal family, securing exclusive contracts to renovate the holiest sites in Mecca and Medina. After his father died in a 1967 plane crash, Osama inherited a share of the fortune—estimates range from a few million to as much as $300 million. He was educated in Saudi Arabia and mentored by a Jordanian scholar named Abdullah Azzam, who pushed him toward Salafism, a puritanical, literalist interpretation of Islam. Bin Laden’s version of jihad was offensive and violent: he believed it was a personal religious obligation for all Muslims to wage armed struggle, not ju

This week on Historically High, we begin our two-part deep dive into September 11 by pulling back the curtain on everything that led to that fateful Tuesday morning.

To understand how four commercial airliners were turned into guided missiles, you have to rewind decades. We start in the brutal, scorched valleys of the Soviet-Afghan War, tracking how the mujahideen resistance gave birth to both the Taliban and al-Qaeda. From there, we trace the rise of Osama bin Laden and Ayman al-Zawahiri, the bloody trial runs that the world largely brushed off—from the 1998 U.S. embassy bombings in East Africa to the suicide strike on the USS Cole—and the tactical evolution of Khalid Sheikh Mohammed’s deadly "planes operation."
We break down how al-Qaeda slipped hijackers into American flight schools right under the nose of U.S. intelligence, the bureaucratic blind spots that let them train in plain sight, and the chilling final logistics locked in place on September 10, 2001.

Light up, settle in, and join us as we connect the geopolitical fuse that was lit years before the towers fell.
