2011-07-05 - In flight (between UK and Netherlands)

high speed object from commercial flight, spotted over North Sea

I can not be sure of how valid this report is, but in July, whilst staring from the window of a Finnair flight from London Heathrow to Helsinki-Vantaa I saw what appeared to be a spherical shape in the cloud not far from our airliner, I could not get a very clear picture but I did note what appeared to be a disk-like shape and the fact that it seemed quite motionless in the cloud. I saw no exhaust being emitted from the object, as we approached, it flew off in a southerly direction into the clouds, it seemed to be sharply turning in a South-Easterly direction at a high speed. I know little about aircraft although even in the distance it seemed to be travelling very fast. This was when we were flying across the North Sea towards what must have been the Northern areas of the Netherlands.
