Pronews 7's Lindsey Stiner spent time with these now high school seniors to get their perspective on that day, and how it's changed over the years.
It was almost exactly 10 years ago, when the world watched the horror of 9/11 unfold. Through our memories and video from that day, students who at the time were too young to grasp its meaning can now reflect, pull some understanding from it, and talk about it.
These students are using "Celebrate Freedom Week" to discuss 9/11 and share their stories and feelings. Many just remember being in their second grade classroom.
"I just remember my teacher from across the hall coming into our classroom and just like not really telling us, but her, what had happened and everybody in my class didn't know what was going on and my teacher just sat there in shock, she didn't know what to think. When I got home that day my parents tired to explain, but I was too young to realize, comprehend what was going on," said Austin Castillo, Randall High School Senior.
"I remember my second grade teacher, she walked in that morning before school and she was crying but she wouldn't tell us why. I went to a Christian school at that time and then when it got toward the end of the day she had told us what happened and we all prayed together. I didn't really understand what was going on," said Ally Schniederjan, Randall High School Senior.
But as these 10 years have passed, these students say classroom and family discussions have only piqued their interest in finding answers. The replayed images of that day, of the plane hitting the second tower and watching people jump in desperation, deepens their understanding and their emotional response.
"It definitely impacts me now that am older. We watch videos of people like jumping and just the terror people are experiencing and it just makes me feel sick to my stomach," said Schniederjan.
"I was able to learn over the years what happened. I was able to see how important, like devastating that day was to Americans and why everybody was so sad and scared," said Castillo.
To this day, many Americans find it hard to talk about 9/11 without shedding tears, and reliving the fear.
"Celebrate Freedom Week" was created in 2001 by the Texas Legislature as a voluntary program for schools to educate students about the sacrifices made for freedom in the founding of this country.
