Strange Aerial Craft Photographed over Colwyn Bay in Great Britain

Colwyn Bay, Great Bin – 08-15-14
Whilst out walking on the beach at Llanddulas at a approx. 7 am, I had stopped to watch some sea birds diving down into the water about 30 meters off the shoreline. 
 
As I watched, a weird solid structure appeared in the sky above them to the North and moved slowly towards the beach. I thought at first it was a balloon, but it was very solid and metal looking.
I quickly grabbed my mobile phone and took a picture of it as it turned left and moved in an Easterly direction. It looked like it had a pair of dipped wings or something hanging down from it on each side, but it was also a bit pointed at the front.
 
It made a slight humming sound, and it had white and blue lights that seemed to glow or pulsate. As it turned to the East they changed to a yellow color. 
 
I would say that I watched it for approx. 90 seconds and as it moved down the coastline. It did seem to change shape slightly.
It then just disappeared about a mile away from my position on the beach. There were a couple on the beach who may have seen this too because they walked behind me as I was watching it. I think they were foreign though, because they were quite tanned and spoke to each other with an accent so I didn’t say anything to them.
I am familiar with aircraft and this was 100% no helicopter or fixed wing craft and certainly no weather balloon because this was moving in a controlled manner.
