The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
This white circular disc-like object moved at average speed (about as fast as a low-flying aeroplane) directly overhead above the car park. it was about 200 feet up in a partially cloudy sky and it moved from west to east. it went over the horizon and was visible all the time. its shape was unlike any aircraft (or balloon) i had ever seen before. it was about the size of a commercial aeroplane. two other people in the car park also saw the object, after i pointed it out to them. they confirmed the sighting.
