I was glad to hear the meaning of the word "Dominie", which was new to me, thanks folks.
Just to add to this fund of "rambling, probably useless, but nonetheless interesting info" - to me anyway, Kittyhawk, you may care to know that the Rapide (in Dominie guise) was also operated by the RAF in UK during WWII as a nav trainer. And I'm not sure, but think it may have been used in the same role in the Empire Training Scheme - i.e. in Canada, Rhodesia (as was), etc.
And just to go a stage further with that name, in the 1960's/70, De Havilland at Hatfield (both as was) developed a twin rear-engined "T"-tailed biz jet called the DH 125. (Of course with all the aviation industry mergers, etc, around that time, and after the "marketing flower arrangers" and other "brand image consultants" got their hands on it, it "ended up" being called the HS 125, which after further "industry consolidations" was stretched a bit and became, I think, the Hawker 800.
Anyway, the RAF bought a batch of the HS 125's for use as navigation, etc, trainers and called them - yep "Dominie". Don't know if they're still in RAF service these days though.
