UK is Reading in to it??

The object seemed to hover over along period of time over a particular area, the shape of the craft was kind of a oval saucer shape, and it had lights that were green, red an blue, that flashed at periodical times, in no given order.Then it would move position an go further up into the sky an then back down to its previous position, it did this for appoximatly 5 minutes, and then after this it just flew what semmed a very long distance away, an repeated the same things over again,area/place we saw the object was in a place in the UK/England around a 5 mile radious of Reading, Berkshire, it is unknown as yet if there are any other witnesses who have seen this? on another note,we also saw aircraft flying that night (planes), that seemed to just avoid the area where the object was hovering!!??
The report appears to us to be not inconsistent with a twinkling star.  However, that is only conjecture.  Witnesses elect to remain semi-anonymous.  PD
