For decades I have searched archives for rare documents and interviewed aviation witnesses. With the free distribution of many of documents from my collection, I would like now to help other historians and motivate young people to also devote themselves to the many exciting puzzles of aerospace history.    These Downloads are intended for private use by aviation enthusiasts only and may be shared with friends. You will also find books I would like to recommend to you. This is my mission. I see myself as a part of the community of historians and would like to share my findings and - of course - the joy of research with others! Uwe W. Jack

If you would like to find out more about the history of the Junkers Ju 287: The most advanced Jet-Bomber of the Luftwaffe One of the world’s first aircraft designed with swept wings would have changed the air war in 1945 if the Luftwaffe had managed to deploy the Junkers Ju 287. Prototypes were built and tested by the Luftwaffe in 1944/45 and in the USSR after the war.    Lots of photos, drawings, information, data and more than 6000 words give a detailed insight into the development of this unique piece of aviation.    Uwe W. Jack in 1990 discovered documents that proved that all other publication to date on this aircraft had been wrong. He met the chief test pilot of Junkers, who had flown the prototype of the Ju 287 and got first-hand information on its behavior in the air. Uwe W. Jack shared his knowledge liberally with other authors - but now publishes his version.
