🇺🇸 USAF — Project Blue Book
In 1951, near Fort Worth, Texas, a group of people observed a triangular formation of lights. Witnesses reported the lights were red and green, moving slowly at an estimated altitude of 1000 feet. The phenomenon caused confusion as several people observed it simultaneously. Although explanations such as balloons or aircraft were considered, no definitive conclusion was reached. The witnesses' descriptions and the absence of typical aircraft sounds added mystery to the case.
