On Sep. 11, 2001, terrorists hijacked four civilian passenger jets, crashing them into the north and south towers of the World Trade Center in New York, the Pentagon in Washington and a field in rural Pennsylvania.
At least 18 Colorado Guardsmen were in Washington on that fateful day. One barely escaped the attack and a former Colorado Guardsman was killed. For their stories, read 9/11 in their own words.
Here in Colorado, by the day’s end, the roar of F-16s patrolling overhead broke the otherwise deafening silence in the sky, and troops across the state were charged with keeping watch on the ground.
In total, more than 3,000 civilians were killed in the attacks.
