Take The Quiz To Test Your Knowledge About 9/11

Osama bin Laden was the mastermind behind the 9/11 attacks. As the founder and leader of the terrorist group Al-Qaeda, bin Laden orchestrated the coordinated hijacking of four airplanes by 19 terrorists. These terrorists then carried out suicide attacks by crashing two planes into the Twin Towers of the World Trade Center in New York City, causing their collapse, and another plane into the Pentagon. The fourth plane, United Airlines Flight 93, crashed into a field in Pennsylvania after passengers attempted to regain control from the hijackers. Bin Laden claimed responsibility for the attacks, which resulted in the loss of thousands of lives and significant destruction.

No evidence has been shown to support the connection between Saddam Hussein and 9/11. According to a 2007 Newsweek poll, however, 69% of Americans still believe that Saddam Hussein was involved in the 9/11 attacks.

The estimated death count after the disaster was 3000 people.

In 2007, former Director of Central Intelligence George Tenet said, "We could never verify that there was any Iraqi authority, direction and control, complicity with al-Qaeda for 9/11 or any operational act against America, period." A 2003 Washington Post poll, however, revealed that 30% of Americans believed that Al Qaeda was connected to former Iraqi president Saddam Hussein.

Two planes (American Airlines Flight 11 and United Airlines Flight 175) crashed into the North and South Towers of the World Trade Center and one plane (American Airlines Flight 77) crashed into the Pentagon. However, the passengers of the final hijacked plane (United Airlines Flight 93) fought back and the hijackers crashed the plane into a former coal mine near Shanksville, Pennsylvania.

U.S. homeland security secretary Janet Napolitano falsely stated in 2009, "To the extent that terrorists have come into our country or suspected or known terrorists have entered our country across a border, it’s been across the Canadian border. There are real issues there. (…) Not just [the 9/11 hijackers] but others as well." However, the 9/11 Commission has determined that the hijackers came to the United States from overseas.

AT&T developed the 911 emergency contact number. This was in response to the need for a centralized emergency number that people could call in case of emergencies. AT&T played a crucial role in establishing this system, which has since become a vital lifeline for people in distress.  The technology of 911 has changed over time, but Haleyville's call proved the concept worked.

Although former President George W. Bush stated in 2005, "This war reached our shores on September 11 2001," to try to restore confidence in the war effort, Iraq has never been proven to be connected to 9/11.

On September 11, 2001, terrorists targeted the Twin Towers of the World Trade Center in New York City, the Pentagon in Arlington, Virginia, and United Airlines Flight 93, which crashed in a field in Shanksville, Pennsylvania. While the White House was considered a potential target, it was not directly attacked on that day.

The correct answer is 18. This means that out of the given options, 18 people were saved from the rubble.
