Most of us can remember where we were and what we were doing on Sept. 11, 2001 — the day terrorists flew highjacked planes into the World Trade Center towers in New York, the Pentagon and a field in Pennsylvania.

But what about those of us who weren’t born yet?

“I know it was a very sad day when it happened,” said 10-year-old Megan Wieger, a fifth grader at Brandywine Elementary School in Niles. “Ever since I can remember when I started school, the principal would come over the loud speaker on 9/11 and ask everyone to take a moment to remember the people that were killed that day. It’s just very sad.”

Ten-year-old Dominick Thornton, also a fifth-grader at Brandywine Elementary, said he was very young when he first learned about it — too young to remember how or when. He has seen pictures of the Twin Towers coming down and the destruction it caused.

“It just kind of scares me that somebody would do that,” Thornton said.

Brandywine fifth-grader Justin Reske can recite the basic facts from 9/11. He knows that terrorists highjacked several planes and flew them into the Twin Towers and the Pentagon. He’s even watched videos taken that day at home.

“I just can’t think why anybody would be able to do that. It’s just inhumane,” said Reske, 10.

Brandywine sixth-grade teacher Nancy Mitchell said the number one question her students ask about 9/11 is: “why would someone do something like that?”

“They are very interested,” Mitchell said. “They just can’t believe it happened.”

Mitchell said she’s been teaching her students about 9/11 all week.

“I think it’s important to teach it because they can see how, even with something so horrific, that people can band together and help each other out,” Mitchell said. “I think it is a good thing to teach at the beginning of the school year because, as a class, they feel more bonded together after studying it. I know it sounds strange, but it’s true.”
