• Apollo 1 made cabin atmosphere and test configuration a crew-safety accountability test

  Apollo 1 was not simply a spacecraft fire whose lesson was to remove one bad material or replace one difficult hatch. It was a ground test in which a sealed cabin, pure oxygen above ambient atmospheric pressure, distributed combustibles, vulnerable wiring and plumbing, slow egress, weak emergency preparation, communications trouble and a test classification that did not match the real hazard all met at once. The accountability test is whether the institutions controlling those conditions could see them as one coupled crew-safety system before three astronauts entered the cabin—and whether later repair can be proved without turning a safety investigation into a legal verdict or a redesign into a claim of permanent safety.

• Space Shuttle Columbia made foam-strike normalization an organizational-learning accountability test

  Columbia was not lost because NASA lacked warning signals. Foam had escaped from external tanks before, a large bipod-ramp loss had occurred on the flight immediately preceding STS-107, launch imagery showed the new strike, engineers sought better images, and the in-flight analysis carried major uncertainties. The accountability failure was that these facts did not acquire enough authority to stop routine reasoning. A breach in the left wing destroyed the vehicle during re-entry; a system for classifying, escalating and disproving hazards had already converted repeated noncompliance into accepted experience.
