Domain-specific¶
- Integer Overflow
- The overflow raised an operand error the surrounding code did not handle; the module shut down, its diagnostic output was misread as flight data by the backup computer, and a destructive attitude correction about 37 seconds after launch drove the vehicle to an angle of attack under which it began to break up at about 39 seconds.
This sourceThe official inquiry board report establishing the unhandled Operand Error in the horizontal-bias conversion, the shutdown of both inertial reference systems, the diagnostic bit pattern consumed as flight data, the destructive attitude command at about H0+37 s and the launcher's break-up at about H0+39 s under an angle of attack above 20 degrees.

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 1 citation: 1 supported. 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.
