I don't think any engineers deemed any available information about Columbia as "insignificant", not that there was very much information to go on due to lax execution by camera tracker teams. Management on the other hand was... not effective. I think that's really the crux of your statement. Humans seem to be terrible at working together in large organizations, or at least running them. Organizations seem to learn from mistakes only temporarily, or at all (as you pointed out). Consider the self-driving car group at Uber as a recent example.
