UFO's spotted over the midlands?

So there has been a news report that UFO's have been spotted over the Midlands in England.

After watching the video it does seem quite strange that there are so many lights in one place and I can't think of any sort of explanation for them.

Have a look for yourself and see what you think of them to be.
No doubt some prank or completely logical explanation for it, but what if the aliens really are coming? Perhaps it's time to dawn tin foil helmets and bulk buy butt plugs so they can't invade you.
