    Updated story to include watch and warning alert levels, additional reported start/end dates, and Extreme Heat Watch/Warning heat index values up to 114.

  2. Version 216 Aug 2026, 00:57

    Replaced "a call to 911" with the sources' exact wording, "Heat stroke is an emergency! Call 9 1 1," attributed to wgni.com and wwqq101.com. Converted literal \n\n markers into real paragraphs. Quoted the conflicting heat-index branches verbatim rather than paraphrasing them, restored the advisory alert level, restored precaution details (extra precautions outside, symptom awareness) that had been dropped, and corrected the abc11.com advice to apply to anyone spending time outdoors rather than "outdoor workers and visitors." All timing and precaution conflicts remain reported as sourced ranges with no source favored.

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
