Mysterious Ring Of Lights Spotted Over Arizona Again

Either large flocks of birds are now wearing bicycle lights for added safety or something odd is happening in the US.

For the second time in 12 months, a large grouped ring of lights has been spotted hovering in the sky suggesting that not only is it a UFO, but one that has been around for some time.

The latest sighting was over the Estrella Mountains in Arizona where a driver was able to capture the collection of lights appearing in the distance.

These echo the images captured by numerous people back in August 2014 when a mass sighting of the lights over Houston in Texas caused videos and images to flood onto the web.

Some have suggested that they're a swarm of drones, or a formation of aircraft while others have gone for the far more interesting -- but categorically less likely -- suggestion that they're a formation of UFOs.
