Answer:
Explanation: The incident which took place at September 11th, 2001 was famously called the 9/11 incident
19 terrorists hijacked four commercial airliners scheduled to travel from the New England and Mid-Atlantic regions of the East Coast to California.
The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, two of the world's five tallest buildings at the time,
and aimed the next two flights toward targets in or near Washington, D.C., in an attack on the nation's capital.
The third team succeeded in crashing into the Pentagon, the headquarters of the U.S. Department of Defense in Arlington County, Virginia, while the fourth plane crashed in rural Pennsylvania following a passenger revolt. The attacks killed nearly 3,000 people.
