I have marked this book harshly because it is not a history of the DH Comet, regardless of the claims of its cover and the Air-Britain publicity. Instead the majority of the book, 250 pages, concerns the use and fate of each of the Comet airframes.
Despite ``25 years of research'' the author appears to have taken little time to investigate or document the origins and design philosophy of the Comet and the six written pages dedicated to this topic offer little additional information beyond the most cursory of web pages, though even those wouldn't make such gaffes as claiming that the Avon was the first axial-flow jet. Variants are introduced without any discussion of their development and little is added by the seven-page operational history.
The brief Operators and Simulators chapters provide some interesting information, the former offering sample timetables, but too soon this gives way to the interminable pages of minutiae about check flights, routine airline operations and transfers between airlines or units. Whilst ownership details and flight hours are recorded in excruciating detail there is complete opacity with regard to less accessible history, such as the antics and equipment of 51 Squadron's Comets.
Admittedly there are dozens of unique photographs and there may well be several fascinating anecdotes, but to find them you will have to read each of the airframe entries in sequence. I could manage about two at each sitting before tedium seized my mortal mind.
If you would like to know what damage G-APDT suffered during a landing-gear failure in Baghdad then this might be your five-star choice. If, however, you want to learn how and by whom the Comet was designed and built, what it was like for its passengers and how it changed British aero-engineering then this book will leave you disappointed and very much out-of-pocket.
