Saying "we almost lost Atlantis" only confirms the point that they could have mitigated the foam lost before Columbia, and they could have fixed the O-Rings before Challenger. Not investigating those incidents properly, is a human factors failure. I do agree that design decisions like side-by-side staging of SRBs wasn't the safest choice. Safer abort scenarios is definitely a feature of Dragon.
