Osprey in South Somerset about 1600 hrs. Showed up on Freedar, sort of. The aircraft code was lots of zeros. The initial flight paath was sawtooth in the horizontal plane but as it got nearer to Yeovilton it straightened out. and appeared to to do an approach/go around. Headed back towards Newbury about 1610hrs. I only had a phone with me and the attempted photo was embarrasing!
