An Illinois witness at Oak Brook reported watching a triangular-shaped object hovering over Salt Creek that “disappeared instantly,” according to testimony in Case 87318 from the Mutual UFO Network (MUFON) witness reporting database.
The witness was a passenger in a vehicle traveling northbound along Washington Street heading toward Spring Avenue at 7:10 p.m. on October 13, 2017.
“My girlfriend was driving and asked, ‘is that a plane, it's not moving,’” the witness stated. “I looked up and saw a black triangular craft in the sky at a relatively low altitude – maybe 1,000 to 2,000 feet. It slowly drifted maybe 100 yards to the southeast over the course of about one minute and then just disappeared completely.”
Illinois MUFON State Section Director William A. Leone closed this case as an Unknown – Other.
