"PS Is this a UFO at Gray Hill just to the right of the B52 ?
PPS I have not doctored this image. If anybody wants the version direct from the camera, just psot the request in this forum :-)"

I saw the very same objects as shown in your photo several years ago at an red arrows air display. In fact there were several of these objects that appeared to be very high altitude. I guess they're sending back data on whether conditions at altitude?
