Peter Duffy: he wrote a very good book some years ago, called "Comets and Concordes (and those I flew before)," about his flying career, which included the Comet 1 with BOAC.
The book jacket (from 1999) states that he was born in 1925, so he'll probably be 87 now, if he's still with us (and I very much hope he is). It also stated that he was living then in Vancouver. Send me a PM if you want any more detail, such as name of the book's publisher etc.
