Background
1. On August 14, 1975, a helicopter pilot and air traffic controllers near Stockton, California, observed a diamond-shaped UFO. The object exhibited unusual flight characteristics and was tracked by multiple witnesses. This event occurred during a period of increased UFO sightings in northern California.
The Incident At 9:35 p.m., Major Claude Riddle was flying a helicopter at 900 feet, approaching Stockton Metropolitan Airport. Air traffic controller Joe Savage observed flashing lights on a collision course with the helicopter. Savage advised Riddle to take evasive action.
The object then turned orange and rapidly ascended to 5,000 feet, where it hovered. Riddle, looking behind him, saw a light trailing his helicopter about a mile away. When he turned towards the light, he saw an object "shimmering like a diamond."
Riddle described the object as oval-shaped, jetliner-sized, and radiating a bright orange glow from the top. He also noted two blue beams emanating from the sides of the object. Another air traffic controller, Dan Long, also witnessed the glowing object through field glasses.
