Before everybody goes all judgemental, it COULD be that he flew the jets on his free time in order to keep current on fast jets while spending all his professional time flying a desk at headquarters.
Compared to frontline jets, a jet trainer has relatively low flight costs. Arranging the refueling stops on a training mission to coincide with something pleasurable is an old international airforce tradition. It is all a matter of avoiding excesses.
The helicopter? Well.. it is on a training mission to Isle of Wight
