Sometimes even teachers don't know

I read this book to my students today. It's about a fireboat that helped in New York City on September 11th.

Here's what they wanted to know.
"Was it an accident?"
"Why did that happen?"
"Why weren't the pilots watching where they were going?"
"Who were the bad guys?"
"Were you there?"
"Did they crash into the buildings because they were jealous we had really tall buildings?"
"Is it going to happen again?"
