United States.Stephenville
Dozens of witnesses — including a constable — reported a large, silent object over Stephenville, Texas; FAA primary radar data obtained via FOIA correlated a track heading toward the restricted airspace of the presidential ranch.

Incident
Limited evidence: single-witness, local or without primary verification. Three independent axes: the «tier» measures the strength of the evidence; the «probability» estimates how genuinely unexplained the case is —a natural phenomenon can remain unexplained, so it does not equal «non-prosaic»—; and the partition of explanations (below) says what it most plausibly was. So a well-documented case can have a possible hoax as its most plausible cause, and a Tier B is not, for that reason, a hoax.

Part 01
The night in question
On January 8, 2008, around 18:15 local time, multiple residents of Stephenville and the surrounding rural areas (Erath County, Texas) observed a large, silent object with bright lights moving at low altitude. The most cited testimony was that of Steve Allen, a private pilot with decades of experience, who described a large structure —on the order of hundreds of meters— moving silently at very high speed and, by his account, pursued shortly afterward by jets. Constable Lee Roy Gaitan watched the lights with his son and neighbors; other independent witnesses included farmers and residents across the county. The convergence of independent accounts of a silent, low-flying object is the case's first pillar.
The second pillar is instrumental. Researcher Robert Powell (then MUFON director of research), with radar analyst Glen Schulze, requested the FAA's radar data for that night under the Freedom of Information Act (FOIA) and reviewed on the order of 2.5 million return points. The report identified primary radar returns without a transponder —objects the radar saw but that were not identified as cooperative traffic— temporally correlated with the sightings, some at very high speeds. Critically, by the analysis, one of those tracks followed a heading that took it on a slow approach toward the restricted airspace of George W. Bush's ranch in Crawford, coinciding with the president's presence. The same dataset confirmed F-16 jets operating in the area, which the report treated as objects distinct from the unidentified track.
The third axis is institutional. Initially, the area's military authorities denied having any aircraft aloft that night. Days later, the 301st Fighter Wing reversed course and confirmed it had been conducting F-16 training exercises in the area, attributing the prior denial to a communications error. This correction underpins the dominant conventional explanation: that part of the sightings were F-16s in training, whose lights and reflections could be misread, and that the reported sonic booms came from those same jets. That mundane reading is plausible for some of the reports, but the case's proponents argue it does not exhaust the testimony of a single large, silent object, nor the radar track heading toward Crawford at unusual speeds. The 301st has not clarified the discrepancy in detail. The case is one of the few with exhaustive FOIA analysis of FAA primary radar published by MUFON in an extensive technical report.

Why this case moved the needle
It is one of the few corpus cases that combines convergent civilian testimony with an exhaustive FOIA analysis of FAA primary radar, plus the aggravating circumstance of a track heading toward restricted airspace during the president's presence at his ranch. Its methodological value is high: it shows how civil, legal tools —an information request and the scrutiny of millions of radar points— allow an event to be reconstructed objectively, without relying solely on witness memory. That is the model later cases have sought to replicate.
The 301st Fighter Wing's initial denial followed by a correction is a clean institutional data point on military communication behavior during public events: a first denial, later reversed, that —whatever its cause— erodes trust and feeds suspicion of cover-up even when the final explanation (F-16 exercises) is mundane. For calibration, the case lives in a productive tension: the conventional explanation covers much of the reports, but the unidentified radar track toward Crawford and the testimony of a single silent object keep it from full closure, which justifies its position at Tier B with intermediate probability.

Distribution of explanations
This case is classified among the model's hypotheses: the bar splits 100% by how much each explanation weighs (the uncertainty is spread across the hypotheses the case supports). Summed across the corpus they produce the comparable partition. It is a different question from the Probability above: that one estimates how likely the case is a genuinely unexplained phenomenon; this one splits which the explanation would be.

Structured analytical judgment, not a calibrated frequency. Forced classification: the mass the evidence cannot assign is spread across the hypotheses the case does support.
