I thought we had two, and that they were part of Boscombe Down wierdness. However, this
website implies that we have 10 with Aircraft Test & Evaluation Sector (?) and ETPS at Boscombe, and 2 at Llanbedr, which I thought had closed. As they're on the RAF register, I'm sure some spottery website will list the individual aircraft.
I was bounced by two of these bstds at low level about a year ago, one tight down each side of the wokka at 50ft+not much.
ps I think they're kept in the same hangar as the crashed UFOs
