At the 9/11 museum I learned the unfortunate fact that Flight 93 flew upside down for a period of time before crashing in the field. Apparently, people all over the plane were vomiting. If you’ve even been on a flight where someone throws up nearby, you can imagine how disgusting, awful, and traumatizing this had to have been. Breaks my heart just thinking about it.
Another sad fact is that 8 children were on those planes. 3 were on a trip to California with their teacher. Two siblings (ages 8 and 3) were traveling with the parents, and after missing their original flight, were put on Flight 77 (crashed into the Pentagon.)
I was in middle school at the time, but nearly 20 years later, 9/11 facts continue to haunt me.
