Still lots of XX registration Hawk T1s flying around. There were lots of XX Jags flying around as well a few years back. Gives a clue as to the vintage of the aircraft in question. Hawk T2s are all ZK___. I believe there are ZZ___ registrations for the Voyager aircraft (I'm happy to be proven wrong on this latest statement though for fear of appearing like a total nerd!).
