Two planes struck the Twin Towers on September 11, 2001.

Event Overview

American Airlines Flight 11 crashed into the North Tower (1 World Trade Center) at 8:46 a.m., followed by United Airlines Flight 175 hitting the South Tower (2 World Trade Center) at 9:03 a.m.

These impacts, part of a coordinated al-Qaeda attack, led to both towers collapsing within two hours, contributing to nearly 3,000 total deaths.

Four planes were hijacked overall, but only these two targeted the Twin Towers specifically.
