Thinking that the mission for Suni and Butch has evolved from 8 day s to 8 months, I'm imagining a NASA recruiting poster saying something like "Join NASA and see the world" - "again, and again, and again.......".
Though I'm certainly not knowledgeable on spacecraft, software, and helium leaks, I do know something about signing on the line saying that an aircraft is fit and safe for fight. I can't blame a staff member somewhere in a suitable safety structure in NASA or Boeing for, in their best conscience, saying "I can't sign on that line with what I know to date". I think back to the congressional investigations following the Apollo 1 fire, where (I believe it was Deke Slayton) said that it was "failure of imagination" "We just did not ever imagine that type of risk". So now, no one wants to be the person who could next be in front of a congressional investigation, admitting that they did not think of a risk - particularly if they work for Boeing!
I remember the old pilot saying "it's better to be down here, wishing you were up there, than being up there, wishing you were down here". I guess that that needs to be changed for spaceflight, to say "better to be up there, then on your way back down, wishing you'd stayed up"!
