Background

Terrorists attacked the United States, and the accepted answers add the specifics: hijackers flew two planes into the World Trade Center in New York City, one into the Pentagon in Arlington, Virginia, and a fourth crashed in a field in Pennsylvania after passengers fought back. Nineteen men from al-Qaeda hijacked four airliners that morning. Both towers collapsed within two hours, and 2,977 people were killed, the deadliest attack ever on American soil. The consequences reshaped the government: the Department of Homeland Security was created, airport screening was federalized, and military campaigns followed in Afghanistan and later Iraq. Those conflicts are asked about in a separate question, so keep this answer to the event itself.

This background section is written by US Citizenship Test Practice to explain the civics fact. It is not part of the USCIS question list, and the official answer above is the one to give at the interview.

It is part of Recent American History and Other Important Historical Information, inside the American History section of the test. It is also one of the 20 questions in the 65/20 set, so it is worth knowing well.
