Retrospective. By Myhra. Based on interviews with numerous former Horten Flugzeugbau members to better understand how the Horten Ho 9 came to be - its construction delays, flight testing, and the loss of test pilot Erwin Ziller in 1944. Through these interviews, the complete picture of both the remarkable twin turbojet powered Ho 9 fighter/interceptor and the production prototype Ho 229V3 is presented. For the Horten Technical History, see item #5922. 200 pgs., 250+ B&W photos, line drawings
