Just reading over this thread has got me wondering.
What if we took the number of white crew people with speaking parts and considered the fraction of them who got killed versus the number of black crew people with speaking parts and considered the fraction of them who got killed.
What would the results be? In other words, among the crew, would the black people who spoke be more likely to die than the white people who spoke?
(I'm restricting this question to speaking parts just so that we don't have to sift through all the extras walking through the background.)
