I recall estimates of one in four from the days of Feynman and the investigation into the Challenger loss. Maybe that was the post crash estimate, but I don't think even NASA would think that one in 10^5 was realistic, as that rate is more like civil aviation in the 1950s and 1960s (with accidents like the Electra). ..
