At what stage was a shuttle loss per 50 flights projected? Can you expand on this, do you have a link? Was that due to the boosters or some other design constraints? Would a smaller shuttle have fared better in terms of reliability?

They started PRA of Shuttle after Challenger [1]. I got that number from the SLS PRA and Reliability people, and might have read it in a report too, but I don't remember many more details about it. There's a lot that goes into PRA [2].

Shuttle size was dictated by intended cargo and maneuvers, so it's not really possible to say how changing size would affect it since you'd have completely different design constraints and objectives.
