As I remember, the other people in the plane at the time were injured due to burns and other debris but survived. We were about 150 feet away from the planes on display and I remember hearing how loud and sudden the explosion was. Not sure what happened my Dad said looks like an ejection seat just went off.
I sometimes think back to that day and always do whenever I hear about or come across stories ejecting from an aircraft and how terrifying it must have been to that kid.
