It's definitely smoke, not insects... and I've lost count of the number of times 'experts' and the media have been 'stumped' or 'baffled' by this phenomenon.
Seeing as I have seen this phenomena about half a dozen times does that not qualify my opinion as an good eyewitness?
I used to pass a very large water treatment plant next to the river thames just west of London every day, sometimes stuck in traffic bumper to bumper. Occasionaly, the rings could be seen hovering above the trees especially in hot weather and I would observe them for ages. I've also seen them at other locations, usually near water treatment (sewage) facilities.
Swarming, dispersing, gathering, moving location.
If you know it's "definately smoke" and NOT insects then please explain what I saw so many times that needed no consideration on my part beyond a few seconds that looked exactly as what's in the O.P.
Go on.....deny my ignorance with facts please.edit on 14/4/2014 by nerbot because: (no reason given)
