One person was killed when a came down near West Glacier, Montana, at about 8:57 p.m. local time on 12 August 2025, according to the accident record held by the National Transportation Safety Board. The investigation is open and this account is based on early official records; details may change. The accident record lists one person aboard and one fatality, and states the aircraft sustained substantial damage. The flight is classified in the record as a Part 91 general aviation flight, and the aircraft is identified as . The NTSB is investigating. The cause has not been determined. Aircraft registry records list as a Nevada Flyboys LLP RV-7A, a single-engine piston landplane, serial number 71130, with a Mattituck TMX 360 engine, registered in the United States. The registry lists the registered owner as Nevada Flyboys LLP; the owner of record is not necessarily the operator of the flight, the pilot, or otherwise connected to it. Registry-derived records compiled by FlightAware and City-Data describe the partnership as having a mailing address in Minden, Nevada, and show a certificate issue date of 25 September 2014 for the aircraft, which is in the Experimental airworthiness class. No public material describing any commercial aviation operations by the partnership could be located. Weather observed at Glacier Park International Airport (KGPI), 18 miles away and two minutes from the reported time, recorded wind from 310 degrees at 3 knots, visibility 10 statute miles, clear skies and 79°F. These are instrument readings at a nearby field and are not a statement about what happened. Geographic reference data places West Glacier in Flathead County, Montana, at a settlement elevation of 3,222 feet, and lists the town as 1.3 miles NW of Ryan Field (2MT1) and 16 miles ENE of Whitefish Airport (58S). That data locates the settlement, not the accident site.

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.
