Opinions Peter J.C. Smith's V-1/He 111 book?

[Marcel van Heijkop]

The following book certainly slipped through my nets:

"Air-Launched Doodlebugs: Hitler's V 1 Missiles and 111/Kampfgeschwader 3 and 53" by Peter J. C. Smith (see: http://www.amazon.co.uk/Air-Launched.../dp/1844154017 )

Opinions/reviews anyone? Is there a lot of new material, such as photos and personal accounts? Worth having?

Thanks in advance,

Marcel
