Originally published by Sqn Ldr Bill Purchase in 2000, the book describes Exercise Northern Venture as it really happened, constructed from Bill’s own personal diary and that of Ced Hughes, another of the participating Chipmunk pilots.
The revised edition coincided with the type’s 75th anniversary (2021-05-22).
Whilst sticking closely to the original narrative the second edition had revised layout, new photographs, and included additional material describing some of the endurance testing involved, how planning was effected, potted histories of all the aircraft involved (as at the time of publication) and included facsimiles of official records of the adventure not previously publicized.
This revised edition is sold out so your only chance to get a copy now is searching on-line, persuasion, or outright bribery. A selection of pages from the book is available here, just to whet your appetite.
