Calvine, Scotland 1990 UFO Photo Evidence

Two hikers in Calvine, Scotland took this compelling photo using a 35mm camera, of a UFO they spotted in the sky on August 4,1990. The hikers were scared and initially hid behind a tree.

The witnesses reported that a military Harrier aircraft approached the UFO and circled it.  That aircraft is also pictured with this UFO craft.

It has been reported that there were originally 5-6 photographs of this incident, but only 1 photograph survives. 
 

Andrew Robinson, who is a senior lecturer in photography at Sheffield Hallam University, conducted an expert photographic analysis of this UFO photograph, and concludes that, "My conclusion is that the object is definitely in front of the camera. It’s not a fake produced in post production, and its placement within the scene appears to be approximately halfway between the foreground fence and the jet in the background."

Is this photo depicting a real UFO alien craft?
