Mystery Stealth aircraft spotted at BAE Warton 18/2/2014

Was passing through Freckleton on Tues so I decided to have a quick look down Stoney lane and saw this coming out from behind the big hangar at pool lane. At first sight I assumed it was the Taranis then obviously the canopy, it’s size and the presence of a vertical stabiliser meant that it must be something else. My guess is that its a full size model for testing in a wind tunnel. If you have any info or thoughts regarding this aircraft please feel free to leave a comment.
