The Ho VIII was by far the largest of the Horten flying wings, and was designed as a commercial aircraft with accommodation for about 60 passengers. Originally to have had a span of 80m, it was to have been powered by six 448kW BMW pusher engines; range was estimated to be 6000km at a cruising speed of between 300 and 350km/h. A prototype was expected to fly in November 1945, but the defeat of Germany prevented its development. The concept was resurrected after the war by Reimar Horten, who went to Argentina and incorporated the idea in the unsuccessful I.A.38 tailless cargo aircraft, which flew in prototype form in 1958.
