Triangle over River Grove, IL
A witness account on file, unevaluated. Most of the archive rests here, and honestly so.
The report, as filed
I could make out a contour line that looked like a flat triangle shape object. The brighter light became dimer while the other became brighter, the light hovered over the ground for around 2-3 minutes and then disappeared completely. The sky had some clouds, but normal airplanes coming from O'Hare airport were easily seen and recognized, but that thing had way to bright lights to be an airplane. Also, as an Army Veteran I know that lights do not just hover in the sky for 3 minutes.
Held as-reported from National UFO Reporting Center (record NUFORC #120681). Witness text is preserved verbatim, including its spelling; nothing is edited beyond formatting.
Ask for the records
What would the paper say?
For a dated, located U.S. sighting, FAA radar data and ATC communications are the records most likely to exist. Through Aletheca, the house instrument, anyone can commission the request — filed, chased, and published in the open, refusals included. The draft goes over already written: the records sought, and the date window they would live in.
