That plane didn't crash. It was atacked on the runway by Jones's militia. They shot the plane up while it was on the runway. Ryan was targeted and killed along with many others, including people who were trying to escape Jonestown. Jackie was shot more than once, but managed to crawl into the jungle and hide, as I recall. Several of the children were able to escape into the jungle as well.
LoL… Actually more of a fascination with abnormal psychology and the minds of sociopaths… figuring out what makes the sick bastards tick. Just read a lot and watched a lot of documentaries on the subject.
