A business jet cruising at 35,000 feet (10,668 meters) over southwestern Kansas told air traffic control it was looking down at a “whole sea” of flashing white lights, stretching for more than 100 nautical miles (185 km) with no obvious source. The crew’s radio call survives. The agency’s own paperwork survives too. Between the two sits a case the Federal Aviation Administration logged, filed, and never explained.
The File
The document at the center of this case is an FAA Kansas City Air Route Traffic Control Center (ZKC) report titled “Unidentified Aerial Phenomenon Initial/Closeout,” timestamped 07:54 UTC on September 27, 2022. It reached the research site The Black Vault through an anonymous source who said they had access to the FAA’s internal database, in a message sent in early October 2022. The Black Vault then filed a Freedom of Information Act (FOIA) request, a formal process for compelling release of federal records, which was assigned Case 2023-00488. That request returned only raw air traffic control audio, not the written report text the anonymous source had already supplied, and The Black Vault appealed the omission. John Greenewald published the case file on November 25, 2022, along with an edited audio excerpt and the full raw recording.
What the Pilots Reported
The aircraft involved, call sign N127RR, a Gulfstream GLF4 flying from Portland to Oklahoma City, radioed Kansas City ARTCC while southeast-bound at flight level 350, about 50 nautical miles (93 km) west-northwest of Liberal, Kansas. The crew described a field of flashing white lights below and to their left, not especially bright, visible continuously for over 100 nautical miles. No evasive action was taken. On the recording, pilots and controllers can be heard speculating about a stadium event or a concert drawing a large crowd below. No one on the tape settles the question.
The Official Answer
The FAA’s own classification for the event goes no further than “Unidentified Aerial Phenomenon.” That label, as The Black Vault’s reading of the paperwork makes clear, functions as an acknowledgment that pilots reported something and controllers logged it, not as an investigative finding. The Black Vault states plainly that it conducted no independent inquiry of its own; it archived a report and left it there. There is no weather-balloon finding here, no test-flight explanation, no misread-instrument conclusion. The file simply stops at a category.
The Ground Theory
Outside the official record, a discussion thread on the Metabunk forum, run by Mick West, took up the case after publication. Contributors there identified a second aircraft that had reported the same lights: JetBlue Flight 136, registration N639JB, which placed the sighting at its 1 to 3 o’clock position. That identification came from Metabunk’s own analysis of ADS-B Exchange flight-track data, not from anything in the FAA file itself. A contributor identified as Keith Foster argued that every center-pivot irrigation system in southwestern Kansas carries strobe position lights, active that September during a drought that had crews watering newly planted winter wheat. West and other contributors proposed oil-well or irrigation lighting near the town of Beaver in the Oklahoma panhandle as the likely source, lining the flight-track data up against known ground installations. The Black Vault reposted the discussion with permission but neither endorsed nor rebutted it. It remains a forum hypothesis, not a finding tested against the FAA record.
What the Tape Doesn’t Reconcile
On the raw audio, the pilot of N127RR first describes the lights as being on the ground, then later says they tracked the aircraft for at least 50 nautical miles (93 km). The two descriptions are hard to square. From 35,000 feet, a fixed, ground-based light field should not appear to move with a departing jet. The recording contains no follow-up question from the controller pressing on that point, and no written amendment exists in the material that has been released to clarify it. The contradiction sits in the transcript unexamined.
The Missing Pages
The written incident-report text that the anonymous source originally gave The Black Vault, the subject line and remarks quoted above, does not appear anywhere in the FOIA Case 2023-00488 release. Only audio came back. The Black Vault filed an appeal over the absence, and no published material states how that appeal was resolved. That is the entire fact: a document is missing from the official release, and the outcome of the challenge to that gap is not on record anywhere public.
What Stays Open
Nothing in the FAA file confirms or rules out the irrigation or oil-well explanation. It was proposed after the fact, by people with no access to the closeout report, and it has never been tested against the agency’s own record. The unresolved part of the case is narrower than that, though: two separate flight crews independently described the same field of lights, visible for more than 100 nautical miles from 35,000 feet, with at least one pilot reporting that it appeared to follow the aircraft. No document, not the FAA’s, not The Black Vault’s, not Metabunk’s, resolves how a ground-based light source does that. If you can tell the difference between what a record actually says and what people later decided it meant, that gap is exactly where this case stays.
