Korea: Huge discs pace US Navy planes
Three US Navy aircraft on a mission 100 miles south of the Yalu River in Korea encountered two large discs approaching from below at high speed. The objects halted, maneuvered erratically, jammed radar and radio, then departed rapidly.
Background
Incident
In September 1950 at 7:00 in the morning, pilots of three US Navy aircraft on a combat mission sighted two huge discs approaching from below. The objects were at least 600–700 feet in diameter, moved at 1,000–1,200 mph, and appeared on radar at a distance of 1.5 miles.
Observations
The discs stopped abruptly, withdrew, and showed a jerking behaviour while accompanying the aircraft and circling above and below them. When one pilot activated his weapons, the aircraft radar failed through interference and the radio transmitter was blocked by a humming tone. The objects appeared silver, shaped like a Chinese conical hat with elongated openings from which a copper-green light emerged that shifted to bright pastel tones. A shimmering red ring surrounded the upper part.
Course and Witnesses
The aircraft were 100 miles south of the Yalu River in Korea. US Navy pilots reported the sighting during a combat mission. It was the first UFO report of the war, with no hostile intent apparent.
