No love for anyone questioning NASA on here. This will probably get downvoted to.

I mean, NASA is the one who called in the vendor engineers to answer questions they had. If you didn't get answers to those questions, or if the answers weren't clear enough for you, then NASA needs communicate that. You can't get the information you want if you don't ask the questions. Everyone here is blaming a slide deck (that had the information on it!) instead of asking how NASA could have ignored that information. Slide formatting is a pitiful excuse for lack of due diligence by the recipients of that briefing - the people responsible for the safety of the at-risk personnel.
