The Hijackings

On the morning of 11 September 2001, members of Al-Qaeda executed a meticulously planned series of hijackings targeting major American landmarks. Four commercial airliners were involved:

• American Airlines Flight 11: The first plane hijacked, carrying 92 people, crashed into the North Tower of the World Trade Center at 8:46 AM.
• United Airlines Flight 175: Carrying 65 passengers, struck the South Tower at 9:03 AM.
• American Airlines Flight 77: With 64 individuals aboard, crashed into the Pentagon at 9:37 AM.
• United Airlines Flight 93: 44 passengers fought back against the hijackers, preventing further destruction. The plane ultimately crashed in a field in Shanksville, Pennsylvania at 10:03 AM.

These attacks highlighted the devastating potential of commercial airliners being used as weapons and shocked the world with their scale and coordination.
