319 was with the ‘Boneyard’ ,more recently she was flying with CAM (centre of aviation medicine) at Boscombe Dn and is now with the Reds.
319 is strain gauged for airframe load measurement – as such a useful a/c for fatigue data gathering.
But please note that there is no connection between the recent accident and her transfer to the reds – she had been earmarked for the reds some considerable time ago !
