Keen planespotter and part-time pilot Bill Renny saw the latest inexplicable object over the Kessock Bridge on the evening of Thursday, May 20.
The sighting comes in the wake of several reports of similar incidents in recent weeks of unexplained flying objects being spotted in the night skies in and around the city.
Bill (49), who is employed as a builders' yard supervisor and lives in Anderson Street, has had a lifelong interest in aviation and military history.
"I was born in Renfrew, virtually at the end of the main runway at Glasgow Airport, and my first job was with Loganair which I got because I was always hanging around the airport planespotting," he said.
"My uncle was a pilot and took me up on a flight was when I was very young and I flew solo before I was 19.
"What I saw that evening I cannot reconcile with anything I have seen before. I'm not talking about green men or anything like that. It was simply something I cannot explain."
