MARGO was neither meaningless nor computer generated!!! She was just one of the old school and a good one at that!!
Yes I know, that's my point. All over the UK we have, or had, 5 letter designators that are actually named after someone or something (MARGO, LOVEL, TWEED, DAYNE, and lets not forget, DANDY and BEANO) but the new rules say the only source of designators is now a computer that spurts out pronounceable 5 letter groups that mean nothing at all. A great shame and another case of new regulation making things just a little less interesting.
