I was looking up at an aircraft high up in the atmosphere flying along leaving a vapour trail.

One of the weird things was next to the aircraft was like a weird blue line in the sky looking like a vapour trail but in a slightly darker blue,this stretched past the aircraft and across the sky.Whilst watching the aircraft we noticed two metallic objects high up above the clouds,one was red and one was silver,these seemed to be moving around and at times almost cart wheeling along.The sun glinted off them at various times.A third metallic object joined them from the south and then there were three.They moved around above the clouds for maybe 3 minutes and then one of the silver objects and the red one disappeared.The other silver one moved across the sky glinting in the sunlight at various times.The sky was fairly clear apart from high cloud and the objects were above that.These events were witnessed by myself and my girlfriend.
