Overview
In the early hours of January 28, 2018, a resident of Wilmington, Illinois, reported an encounter with a silent, triangular‑winged entity that glided across the sky at approximately 4:36 a.m. The witness described the creature as “brownish‑gray, with bat‑like membranous wings,” moving westward at low altitude without making any sound. The incident follows a series of unexplained aerial phenomena recorded in the Wilmington area during the preceding weeks, including sightings of large triangular UFOs with shifting colored lights near the local Army ammunition plant.
Witness Account
The witness, who prefers to remain anonymous, told investigators:
“I was sitting on my outside step looking upward when my attention was suddenly locked onto something moving across the sky. It looked like a strange hybrid between an owl and a bat… The being moved shockingly fast. It made no sound and did not flap its wings. Instead, it glided smoothly westward and vanished as quickly as it had appeared.”
She estimated the entity’s size at four to five feet in length with wings spanning roughly five feet on each side, hovering at an altitude of about fifty feet. After the sighting, she experienced a “powerful sense of dread” and reported hearing two loud, low‑pitched screeches resembling bat calls. The witness noted that the creature’s skin had a slight sheen, reminiscent of wet reptilian tissue, and that its overall silhouette resembled a large moth, prompting an immediate association with the regional “Mothman” folklore.
Prior UFO Activity
The same resident recounted two earlier incidents that may be linked to the January encounter. In mid‑December 2017, at around 9:30 p.m., she observed a large triangular craft hovering near the Wilmington Army ammunition plant. The craft displayed three corner lights that shifted smoothly between red, blue, and green, and at one moment emitted a bright white illumination beneath it, giving the impression of a ground‑scanning operation. The object remained stationary for several minutes before moving westward and accelerating away.
A second observation on December 18, 2017 involved “unusual aerial lights in triangular formations” over nearby woodlands and industrial zones. Those lights were reported by multiple locals, describing silent, slow‑moving formations that lingered before disappearing without a trace.
Regional Context
Wilmington sits within a corridor of reported anomalous aerial phenomena that has attracted attention from both civilian investigators and academic researchers. The “Chicagoland Mothman wave,” a term coined in 2017 to describe a spike in sightings of winged humanoids and large, silent craft across the Chicago metropolitan area, includes similar reports from neighboring towns such as Joliet, Bolingbrook, and Naperville. Researchers at the Center for UFO Studies (CUFOS) have catalogued over 30 sightings in the region between October 2017 and March 2018, noting recurring features: triangular shapes, silent propulsion, and multicolored lighting.
While folklore often frames such encounters in mythic terms, investigators stress the importance of corroborating eyewitness testimony with radar data, satellite imagery, and environmental monitoring. To date, no official military or aviation records have confirmed the presence of an unidentified craft over the Wilmington ammunition plant during the December events, leaving the incidents officially classified as “unexplained aerial phenomena” (UAP).
Investigation & Next Steps
Local authorities have filed the reports with the National UFO Reporting Center (NUFORC) and forwarded the details to the U.S. Department of Defense’s Unidentified Aerial Phenomena Task Force for review. Investigators plan to cross‑reference the timeline with FAA flight logs and radar sweeps from the Chicago Center to determine whether any conventional aircraft were operating in the area at the reported times.
The witness has agreed to participate in a follow‑up interview and to provide any additional evidence, such as photographs or video recordings, that may have been captured inadvertently. Researchers emphasize that while the descriptions are vivid, the lack of physical evidence necessitates a cautious approach. Continued monitoring of the Wilmington vicinity, especially around the ammunition plant and nearby wetlands, is recommended to identify any recurring patterns that could help differentiate between atmospheric anomalies, experimental aircraft, or other explainable sources.
