Summary (tl;dr)

Searches related to the "9/11 attack" are trending due to today marking the 25th anniversary of the devastating terrorist attacks that occurred on September 11, 2001, prompting widespread remembrance and reflection.

Essential Background

On September 11, 2001, 19 terrorists associated with the Islamic extremist group al-Qaeda hijacked four commercial airplanes in a coordinated series of attacks against the United States. Two planes were intentionally crashed into the Twin Towers of the World Trade Center in New York City, causing both towers to collapse. A third plane struck the Pentagon, the headquarters of the U.S. Department of Defense, in Arlington, Virginia. The fourth plane, United Airlines Flight 93, crashed into a field in rural Pennsylvania after passengers and crew members bravely fought back against the hijackers, preventing it from reaching its presumed target in Washington, D.C.. These attacks resulted in the deaths of 2,977 people, making it the deadliest terrorist attack in history and the single largest loss of life from a foreign attack on American soil.
