Fourteen years ago on this day, three Boeing 747s were high jacked by a group associated with the Taliban attacked the Twin Towers and Washington D.C. and killed 3,380 people from 115 different nations. By the numbers here’s how many were affected:

Total Killed in New York: 2,753 people

Total Emergency Response Killed: 403 people

Total Remains found: 21,906 remains

Americans who knew someone hurt or killed on 9/11: 20%

Estimated number who lost a spouse: 1,609 people

Estimated children who lost a parent: 3,051 children

Estimated New Yorkers suffering from PTSD: 422,000 people

The attacks are considered the worst attack on America since Pearl Harbor in 1941. Parallels have been drawn between the two events and both described as day that will live in infamy. Afterward, the fires didn’t stop burning until 99 days after and cleanup cost $600 million. The New York Stock Exchange was shut down for the next six days and 26 days afterward the US began bombing Afghanistan. Here’s the timeline of events on September 11, 2001:
