As the JEFTS at Barkston Heath usually carries out the ab initio training for the joint services, why is HRH going straight onto the Grob 115 at Cranwell rather than the Firefly at Barkston?
Probably because he'll be doing the training under the RAF umbrella, rather than the RN or Army at DEFTS. JEFTS disbanded at Church Fenton in 2003, for better or worse.
