🇺🇸 USAF — Project Blue Book
In October 1967, a witness reported seeing an unidentified object near the Denver Federal Center. According to the report, the observer saw two very bright lights moving in a northeast direction. Red, green, and blue lights were also noted around the object. Although the witness described the experience, they did not complete the official AF Form 117, limiting further investigation. The FAA and local police did not record additional reports about the incident.
The official conclusion was "possible (aIHCHAPT)", suggesting a tentative assessment. The report also mentions that there could have been normal air traffic in the area, such as planes or helicopters, which complicates the interpretation of the phenomenon. The case was reviewed by Air Force investigators, but no conclusive explanation was reached. The testimony, though detailed, was considered insufficient for a scientific evaluation due to the lack of additional information.
