Discorde
A considerable number of the BOAC 707 Captains were ex WW2 and highly decorated. They were mostly from Bomber Command and Coastal Command and there was even one who was a Battle of Britain pilot. I do not think there are any books written by these pilots.
However there is a book by Peter Duffey "Comets and Concordes". He had a very interesting career and there are a couple of chapters of his time on the 707.
