2009-06-30 - Oxford (UK/England) - Rectangle

rectangle shinny glass like blue box in the sky, 3 dimensional and almost holographic.

I am a Paramedic working in the UK. Summer of 2009 a friend and I both saw a rectangle shinny glass like object in the sky. The object was 3 dimensional and almost holographic with different shades of colour to it. I passed the object off as a weather balloon due to the colours and design coming from it . It stayed stationary and look very high up, so it must have been a large object. There were multiple people in the park at the time so many people must have seen it. I also remember a police car being parked at the side of the road next to the park so its possible this sighting was reported. Years later when i spoke to a friend about what we had seen he immediately laughed and went "oh yes the glass box in the sky, don't know what that was". The weather was perfect this day and it was sunny, as the object stayed stationary for a long time and the park was full there must be further witnesses to this object.
