A member of the public in West Kilbride wrote to the Ministry of Defence to report an object harassing a plane near Prestwick Airport.
The eyewitness told of a fluorescent green UFO, saucer shaped.
The pilot could not have missed it as it was level with the plane but say 50' away to its left as they passed each other. The UFO started to tilt slowly downwards.
Once again, a report was filed on the incident by the MoD.
