🇺🇸 USAF — Project Blue Book
In November 1955, two saucer-shaped objects were reported over Corpus Christi, Texas. Witnesses described them as changing colors between blue and purple and moving erratically westward at high speed. The sighting lasted approximately 15 minutes, and the objects were estimated to be at an altitude of over 50,000 feet.
Officials classified the event as possibly a balloon, though a UFO could not be ruled out. Due to insufficient data and the unusual flight pattern, the case was deemed unverifiable. Despite this, it remains one of the most intriguing UFO reports from the 1950s.
