🇺🇸 USAF — Project Blue Book
In September 1956, multiple UFO sightings were recorded in Pueblo, Colorado. One notable case involved four round objects with flashing red and green lights, observed for two hours. Witnesses described them as stationary in the sky and the investigation concluded they were the stars Vega, Alioth, Dubhe, and Capella. Another sighting involved an elongated white object the size of a basketball, moving in a straight path from east to southwest for two minutes, which was attributed to an aircraft. Finally, a bright round object the size of a washtub was seen moving north in a straight line for 30 seconds, and was likely caused by an aircraft.
