I was an ATCA at Luton (when the terminal building was a wooden shed) in 1964/65 and Chrisair was a regular user; they were certainly based at Sywell then. I remember the Dragon as G-ADDH but my memory isn’t as reliable as it was. Chris’ (Roberts) managed the business and his wife Claire was the pilot. At that time they were aspiring to become a ligitimate airline. Again, I can’t rely on my memory over some 50 years but I think Claire might have been ex-ATA. She was tall and quite statue-esq, always flying in a black leather flying suite and boots. It would not surprise me to learn that Honor Blackman had used her as the template for Cathy Gale (The Avengers) and Pussy Galore in Goldfinger. There were very few women flying in those days and the men, especially the Euravia and Autair pilots tried to take the mickey but Claire gave at least as good as got.

Claire Roberts was a Captain on Heralds with BAF during my time there in the late 1970s. She was a indeed a very elegant and charming lady-who would probably have been in her mid fifties at that time? I would have little doubt guessing that she would have been the same lady by the description.
