There is currently an additional special exhibition on there as well, containing first-hand accounts from survivors who were high school students at the time.
Just went there two weeks ago. The main exhibit was horrifying. The special exhibit you mention was even worse if that's possible. These kids just living their lives as written in their diaries and then the unthinkable happened to them.
Yes. A lot of students were on outside working crews creating firebreaks, so the survivor accounts tended to be along the lines of "I was sick that day, I never saw my friends again".
