It was 15 years ago when 2,977 people were killed in the infamous 9/11 attack after the terrorist group al Qaeda crashed two aeroplanes at the North and South towers of the World Trade Center complex in New York City in the United States. 

The unexpected attack took place at 8:46 am (EST) on Sept. 11, 2001, and the date is now observed as Patriot Day in the country every year to remember the victims of the terror attack at the 110-storey twin towers.

Though it is not a federal holiday, several memorial ceremonies are organised on the occasion. The U.S. flag at the White House and other government buildings is flown at half-staff on the day. Also, a moment of silence is observed at 8:46 AM (EST) when the first plane, American Airlines Flight 11, attacked the North Tower of the WTC.
