Yes, quite a lot of things as it happens. Too many to explain here, maybe you should check out some of my hubs. However, I have not yet written about or mentioned what happened on 30th August 2012 at about 9pm in UK - What I saw in the sky was absolutely phenomenal and there were plenty of other people out in public to see it but I just can't seem to find any info on the subject.
What I saw was undoubtedly in my mind what I can only refer to as an alien spacecraft - that's what it looked like! It was glowing amazingly brightly in the sky and yellow-orange colour and looked like two circular modules fused together, each of which was emanating it's own glow. It also had a flashing white light in the center, between the two modules. Whatever it was, it was clearly some kind of advanced technological machinery, it was the most awe-inspiring thing I have ever seen and it was massive.
This was a day or two after a comet is supposed to have caused a sonic boom throughout the local area which was reported by the local press.
