Nine-Eleven 11 September 2001

On 11 September 2011, four passenger US airliners, all heading for California, were hijacked by 19 al-Qaeda terrorists. After leaving Boston, Flight AA11 crashed into the north tower of the World Trade Center in New York at 8:46 am. Flight UA175, also from Boston, crashed into the south tower at 9:03 am. At 8:39 am, the Northeast Air Defense Sector (NEADS) had been alerted about a possible hijacking after one of the hijackers on Flight AA11 made an accidental transmission to flight control. Two F15 fighters were scrambled just before Flight 11 crashed. Flight AA77 from Washington flew into the Pentagon at 9:43 am. At 10:07 passengers and crew members on Flight UA93 learned about the attacks in New York and Washington and attempted to overwhelm the hijackers. They failed and the plane crashed into a Pennsylvania field at 10:10 am. 2,996 people were killed and nearly 6,000 injured.
