The Sighting: June 24, 1947

On the clear, sunny afternoon of June 24, 1947, Kenneth Arnold took off from Chehalis, Washington, in his CallAir A-2 airplane. His primary mission that day was to search for a U.S. Marine Corps C-46 transport plane that had crashed near Mt. Rainier. A secondary goal was to scout out a potential site for a new air charter service. The weather was perfect for flying, with excellent visibility and a cloudless sky.
As Arnold flew near Mt. Rainier at an altitude of approximately 9,200 feet, something caught his eye. At first, he thought he might be seeing reflections from his airplane’s windows, but a quick check confirmed this wasn’t the case. What he saw next would make headlines around the world and forever change his life.
Arnold observed a string of nine unusual objects flying in a diagonal chain-like formation. He described them as crescent-shaped, flat, and shiny, “like a pie plate cut in half with a sort of convex triangle in the rear.” The objects were flying at an incredible speed, which Arnold later calculated to be around 1,700 miles per hour, nearly three times faster than any aircraft of the day.
The formation weaved between the peaks of the Cascade Mountains, flashing brightly in the afternoon sun. Arnold noted that their movement reminded him of “a saucer if you skip it across the water” – a description that would soon evolve into the iconic term “flying saucer” in media reports.
The entire sighting lasted less than three minutes, but it was enough to leave Arnold stunned and curious. He noted the time and location, determined to report what he had seen to authorities upon landing. As an experienced pilot, Arnold was well aware that what he had witnessed was far beyond the capabilities of any known aircraft.
Initially, Arnold thought he might have seen a new type of military aircraft on a secret test flight. However, the fantastic speed and unusual shape of the objects led him to consider more extraordinary possibilities. Throughout the sighting, Arnold remained calm and observant, making mental notes that would later prove crucial in his reporting of the incident.
Upon landing in Yakima, Washington, Arnold first mentioned his sighting to a friend at the airport. Encouraged by his friend’s interest, Arnold decided to make a formal report, setting in motion a chain of events that would bring him unexpected fame and launch the modern UFO era.
