The September 11, 2001 attacks, coordinated by 19 terrorists, were all suicide attacks. Each of the terrorists attempted to kill themselves in attempt to kill others.
2,973 victims and all 19 of the terrorists died on September 11. The terrorists lead a couple of planes into the Twin Towers of the World Trade Center in NY, one plane into Pentagon in VA and yet another into a field in PA.
These commercial planes, run by American Airlines and United Airlines, were hijacked by al-Qaeda. 246 passengers were lead to an unexpected destination, death. Passengers and flight crew attempted to take control of the fourth plane, battling with the al-Qaeda terrorists, and crashed as a result. It is said that this plane was en route to either Capitol or the White House
Aside from 55 military personnel killed in VA, all of those who died were innocent civilians. As a result of the attacks to the World Trade Center, civilians from more than 90 countries died.
658, investment bank Cantor Fitzgerald L.P., employees were lost, significantly higher than the 335 (2nd highest, for a single employer) death toll of Marsh Inc.
The low death toll of less than 3,000 is something to be thankful for. Had al-Qaeda not have been early risers (the first attack took place at 8.46am and the last attack at 10.03am), the death toll would have been significantly higher, al-Qaeda’s attacks would have been considered much more successful and many, many more people would have been impacted today.
At 5.20pm on September 11, 2001, World Trade Center building number 7 also collapsed. A plane crash, however, did not cause this collapse.
