IANAA...but Starliner's problematic history was no secret when these two astronauts signed up for this flight. From a quick skim of Wikipedia, both came from the US Navy - where both were test pilots, with (in his case) plenty of combat experience to boot. Both have previously been to the ISS multiple times, via multiple launch vehicles. Guess: By these astronauts' standards, this flight seems quite low-risk.
