G-ONAD used to be a C421, and I recall a C404 or similar, G-KENT - those who remember Anna-Marie Ash's infamous spoonerism (corrected to Kent Countryside for those who missed it) on the ITN local news a few years ago might enjoy a wry grin.
G-KENT - PPRuNe Pop, was that ever one of yours?
Having disallowed G-BFUC, G-BFUK, etc, how on earth did the CAA let G-FUKM slip through?
