🇺🇸 USAF — Project Blue Book
In September 1964, a military aircraft over Guam recorded the observation of two luminous objects traveling in a straight line. The observers, who were identifying constellations, were surprised by a bright white and green glow. One object left a pulsating white trail, while the other emitted a fainter green light. Both disappeared within two to three seconds without making any sound, which confused the crew. The aircraft's elevation and the absence of noise added to the sense of mystery.
Although initial reports suggested an astronomical explanation, such as a meteor, the detailed description of the lights and the unusual behavior of the objects did not fully match expectations. The officers who reported the incident were highly reliable and their accounts coincided. The lack of physical evidence and the inability to photograph the objects left many questions unanswered, making this case another of the many unexplained phenomena in the night sky.
