As I have posted here before I have a good relationship with RAF Brize Norton, allowing me to fly inside the FRZ with permission.
I have just been told of an event yesterday of a drone flying at approx. 2300ft !
The Pilot reported that on approach to the airfield, 9 miles to the East, he saw a white quad copter drone, Poss P3 or P4 about 3 - 4 wing lengths away at about 2300ft.
ATC said that the position would have been just to the East of Farmoor Resevoir (west of Oxford) and that the time would have been 1423Z.
I am hopefully that this was not anybody on here, unfortunately another idiot helping to kill our hobby
