German secret weapons: books about airplanes and missiles

	"Lippisch P13a & Experimental DM-1" (1993) by Hans Peter Dabrowski	Well-illustrated booklet dealing with the Lippisch projects DM-1 and the advanced P13a, including several rare pictures.
Profusely illustrated with hundreds of illustrations (mainly of scale models), this book is a really comprehensive study about advanced German aircraft projects of late WWII.	"Secret Aircraft Designs of the Third Reich" (1998) by David Myhra
	"The Horten Brothers and their All-Wings Aircraft" (1998) by David Myhra	The superbly illustrated complete story of the Horten flying wings, including extensive coverage of exotic jet-powered projects such as the Gotha 229. Some other German aircraft projects (Lippisch, for example) are shortly described.
Updated and expanded version of 1947 title "German Research in World War II" by same author. Chapters about some exotic secret weapons, but the book core is devoted to German research achievements and organization.	"Secret Weapons of the Third Reich" (1971) by L.E.Simon
	"Les Armes Secretes Allemandes" (1948) by A.Ducroq	Second edition of the original 1947 edition, likely the very first book entirely devoted to the intringuing subject of German Secret Weapons of WWII. A lof of different projects (related to the Wermacht, Luftwaffe and Kriegsmarine) are presented and discussed, even though there is no reference about the original sources. This work has been frequently quoted by a lot of later books and magazines, especially during the fifties.
