Lastly, though one would expect multiple YouTube videos about a credible UFO sighting,
there appear to be none. But there is a video from an identically named "John Macdonald"
who posted an incredibly blurry (240p!) "UFO" video of similar shape from 2014.
I have spent a bit of time trying to figure out where this was filmed. No match yet but the landscape certainly looks as though it could be in the Perthshire region, near where the other sighting was.
