Primes¶
- Benign-Sampling Safety Drift
- In aerospace and high-reliability operations it is the flagged anomaly reclassified as an acceptable in-family condition across successive incident-free flights — a component out of spec treated, flight after flight, as evidence it worked, until conditions exceeded the designed envelope and a late warning was overruled because the empirical envelope had drifted.
This sourceFinds that O-ring erosion observed without failure across successive flights was treated as evidence the design worked, the empirical envelope drifting past the designed one until conditions exceeded it.

- Normalization of Deviance
- A high-reliability spaceflight program observed early that a critical seal component eroded slightly under cold-launch conditions — a flagged anomaly, outside the original design specification.
This sourcePrimary investigation establishing that the solid-rocket-booster O-ring eroded under cold-launch conditions as a flagged out-of-spec anomaly (the seal lost resilience below ~53 deg F while the launch-morning temperature was far colder), and that the eve-of-launch engineering recommendation against launching in the forecast cold was overruled.

Domain-specific¶
- Hazard-Control Decay
- But erosion showed up on flight after flight through the early 1980s without a burn-through
This sourceRecords recurring Solid Rocket Motor O-ring erosion and blow-by on STS-2, STS-6, QM-4 and STS 41-B through the early 1980s, each absorbed into the working definition of acceptable risk. Records the 28 January 1986 Challenger launch in air 15 degrees colder than any previous launch, the failure of the right Solid Rocket Motor joint, and the breakup 73 seconds after liftoff.

“prior to STS 41-B, the O-ring erosion/blow-by problem was infrequent, occurring on a field joint of STS-2 (November, 1981), nozzles of STS-6 (April, 1983) and a nozzle of QM-4 (March, 1983)”

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 3 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
