Also, conditions outside of the plane should matter. The Tupolev you listed was typically poorly maintained and flown to places like Irkutsk or Arkhangelsk, taking off from and landing onto short or poorly maintained runways, often in winter, with technology available in the sixties to the Soviets. The fact that more deaths happened sooner on a modern aircraft built with state-of-the-art technology, flown primarily by its largest users on routes like Dallas to Miami, should be somewhat alarming.
