The author - an American aided by the world's leading Me-262 research fraternity - has, to date, identified some 1200 of the 1500 machines known to have been built. The book lists sequentially each aircraft by Werknummer (Works Number) from prototypes and test aircraft through to all variants of operational machines, together with known pilots, assigned units and recorded flights, and - where known - the fale of each individual aircraft. Where possible, a photograph of an individual aircraft will accompany its entry in the werknummer log. The book contains more than 200 photographs of known machines, with as many as possible being previously unpublished. The book concludes with a chapter dedicated to previously unpublished photographs of partially identified aircraft. The huge interest in the Messerschmitt Me 262 is evinced both by the success of the earlier quartet of books covering the aircraft compiled for Classic Publications by Eddie Creek and J. Richard Smith and by ongoing restoration projects across the globe. This new book, based upon years of meticulous research, adds considerably to the knowledge of this influential design. It will be an essential work of reference for all those interested in the history of the world's first jet fighter.
