On September 11, several attacks occurred at the World Trade Center, Pentagon, Flight 93

Nineteen years ago, nineteen men set off four airplanes to carry out the deadliest terrorist attack on American soil in a mission abandoned by al-Qaeda leader Osama bin Laden.

For generations of Americans, the September 11 edition of “Where were you at the time of Kennedy’s shooting?” And millions more can recall memories of that day like it did last week. The Pentagon, World Trade Center and Flight 93 attacks killed nearly 3,000 people and 9/11-related illnesses continue to cause deaths each year.

While the attacks on September 11 are unforgettable to millions of people, it is an event that others, who were not alive in 2001, had to learn from family members and in classrooms. As with other historical events, education becomes increasingly important as the years pass and September 11 is no exception.

The terrorist attacks on the World Trade Center, the Pentagon, and the crash of Flight 93 killed 2,977 people and injured thousands. The events of remembrance will take different forms this year, as the new coronovirus epidemic continues to limit celebrations, and many will remember the day virtually. Some would read first-hand accounts of survivors and victims or watch news clips and many who were alive to the attacks would remember where those days were.
