Revision history

  1. Version 217 Aug 2026, 14:43current

    Headline rewritten to lead with the hazard (Extreme Heat Warning) and the specific zones from the record \u2014 Salt Lake Valley, Northern Wasatch Front, Tooele and Rush Valleys, Great Salt Lake Desert \u2014 plus the expiry, and no longer opens with the issuing office. Dek now names Utah and keeps the 102 figure, the 13-zone count and the 2:30 p.m. MDT start. Body restructured so the hazard and area lead the first paragraph; attribution now names the source as the alert record issued by the National Weather Service Salt Lake City UT rather than generic "official records." All figures, times, city list and the 9 1 1 formatting are printed exactly as the fact set gives them.

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.
