Attacks

Early on the morning of September 11, 2001, 19 hijackers took control of four commercial airliners (two Boeing 757and two Boeing 767) en route to California (three headed to LAX in Los Angeles, and one to San Francisco) after takeoffs from Boston, Massachusetts; Newark, New Jersey; and Washington, D.C. Large planes with long flights were selected for hijacking because they would be heavily fueled.

The four flights were:

• American Airlines Flight 11: Left Boston's Logan Airport at 7:59 a.m. en route to Los Angeles with a crew of 11 and 76 passengers, not including five hijackers. The hijackers flew the plane into the North Tower of the World Trade Center at 8:46 a.m.
• United Airlines Flight 175: Left Logan Airport at 8:14 a.m. en route to Los Angeles with a crew of nine and 51 passengers, not including five hijackers. The hijackers flew the plane into the South Tower of the World Trade Center at 9:03 a.m.
• American Airlines Flight 77: Left Washington Dulles International Airport in Virginia at 8:20 a.m. en route to Los Angeles with a crew of six and 53 passengers, not including five hijackers. The hijackers flew the plane into the Pentagon at 9:37 a.m.
• United Airlines Flight 93: Left Newark International Airport at 8:42 a.m. en route to San Francisco, with a crew of seven and 33 passengers, not including four hijackers. As passengers attempted to subdue the hijackers, the aircraft crashed into the ground near Shanksville, Pennsylvania, at 10:03 a.m.
