In the 18 years since al Qaeda terrorists crashed hijacked planes into both World Trade Center buildings, the side of the Pentagon, and a field near Shanksville, Pennsylvania, killing nearly 3,000 people, those responsible have yet to face trial.

But after multiple iterations of military commissions, battles over classified information, and allegations of torture, the death penalty trial for the 9/11 mastermind and its additional plotters has finally been set: January 2021. The military jury selection will begin eight months before the 20th anniversary of the terrorist attacks.
