How did osama bin laden hijack the jets?

Osama bin Laden did not personally hijack the jets; he was the mastermind behind the September 11, 2001, attacks orchestrated by the terrorist group al-Qaeda. The hijackers, who were trained by al-Qaeda, boarded the planes after passing through security at various airports. They used box cutters and other weapons to take control of the aircraft and execute their coordinated attacks on targets in the United States. Bin Laden's leadership and ideology inspired and directed the operation, but the actual hijacking was carried out by the trained operatives.
