An ex-military man, trained in aircraft recognition, believes he saw a UFO while out walking his dog.

Richard Gogin was with his dog, Rommel, in the Marks Hall grounds, Coggeshall, when he saw a triangular shape in the sky.

Mr Gogin of Sible Hedingham spotted the shape at about 6pm on Friday.

He said: “I was calling my dog and just above him I saw a white hot triangular shape.

“It was moving extremely fast.

“I tracked it for about four seconds and it disappeared as if someone turned off a light switch.

“I have never seen an aircraft move like that.”

The 35-year-old, who lives in Hawkwood Road with his wife Nicola, spent about a decade in the Army Air Corps.
