X PLANES OF THE THIRD REICH SERIESAn Illustrated Series on Germany's Experimental Aircraftof World War IIInto the arms of the angels went pilots of the Me 163s, however the Alexander Lippisch-designed machine wasn�t quite finished even though it went into serial production. The RLM called upon Heinrich Hertel of Junkers Flugzeugbau to give the aging 163 a complete make over and a make up for all the initial items it lacked _ that is a cruising HWK 509 bi-fuel liquid rocket engine with a dual combustion chamber, tricycle landing gear, C and T-Stoff fuel tanks in the wings to provide longer flight duration, and so on. Although Hertel�s machine was not flight tested under power prior to war�s end the new and improved version now known as the Me 263 was test flown post war in the USSR. David Myhra has assembled previously unpublished photos, state-of-the art digital images, and photos of a 263 scale model to make this book on the 263 a one of a kind photographic reference.
