Spaceflight will never tolerate carelessness, incapacity, and neglect. Somewhere, somehow, we screwed up. It could have been in design, build, or test. Whatever it was, we should have caught it. We were too gung ho about the schedule and we locked out all of the problems we saw each day in our work. Every element of the program was in trouble and so were we. The simulators were not working, Mission Control was behind in virtually every area, and the flight and test procedures changed daily.
We spent a lot of time in simulators. We were going to do it right.
The pilot looked at his cues of attitude and speed and orientation and so on and responded as he would from the same cues in an airplane, but there was no way it flew the same. The simulators had showed us that.
Stories are flight simulators for our brains.
