As an engineer, I know what's at stake. I simulate the crap out of chip designs before they make it to silicon, because the cost of any bugs that escape into silicon is massive. In the case of these two back-to-back rocket failures, this is NOT par for the course. These are very expensive failures. But more importantly, they are really bad PR for the company. One rocket explosion is fine, but two is starting to look like a real problem. It suggests to me that SpaceX is compressing schedules at the cost of quality.
