Sounds like cyclic compression. This is as there's a start and then an unknown end to the compression increased amplitude. That's why I said possible ET stuff. If you take the time to look at the background, you'll see this is a populated area. Usually they do all this spooky stuff in remote areas.where did that sound come from , with the bright flashing light and sound the first thing that came to my mind was a plasma speaker but on a larger scale as for the audio sound if its coming from the same source of white flash then something's odd
Could be CGI or a penny dog and pony circus, but the power and photonic expression upon increase in power amplitude's what gets me.
In power station failures, its light, boom and sparks. A guess. What do you think it is Steve?
