Sadly the tradition is pretty much dead. Cost savings, etc. In the last 10 years or so it's only been the anniversary jets which get names added, usually bearing the Boss's name plus a lucky other (either the Exec or a random JP). Fleet rotation then ensures that this aircraft gets flown by a totally different squadron, and bears the markings for years afterwards. I've seen photos of the XV(R) Sqn anniversary jet on detachment at Gioia during 2011, when I know for a fact that both of the officers named thereon were on ground tours!!
