[QUOTE 2180232, member: 9609"]We get these strange things, they arrive an fly round and round in circles for many many hours at a time .The circles are colossal, may be 30 mile diameter. In the picture you can see the previous contrails that the wind has drifted away, the route of the plane never varies, same circle time after time week after week. Does anyone know exactly what it's doing?

Ooh, that's interesting. We saw similar over York yesterday - never seen it before (and I do often look at the sky and see contrails, so I'm a noticing sort of person). We assumed it was civilian airliners, and wondered why they were looping yesterday when we'd never seen it before.
Maybe it was AWACS - but the only plane we actually saw was far too high to see any detail.
