Tufte makes a good point that the critical information could have been conveyed so much more effectively.

If only the managers had been given a better summary! But I think this is a vast over-simplification.

Even with a crystal-clear summary of the issues, it doesn't always add up to a clear disaster on your hands. Only in hindsight. The shuttle was an incredibly complex system and there were always issues to examine, to fix, to prioritize, to defer. There is just a lot to regularly weigh.
