everything about the Horten and the B-2 spirit are really different from each other, just look at a top down picture of both, the b-2's wing is W shaped, while the Horten is just a flying wing design.
I'm not exactly sure where you got this information. The Ho 229 was never built for stealth, though there were plans to make it harder to detect. Only 2 prototypes ever flew, with a third one almost completed. All three prototypes were for a jet fighter armed with two MK 108s. A stopgap fighter-bomber was planned, along with a considerably larger four engined bomber for the Amerika Bomber project, but neither of these were built. EDIT: I didn't even read that last bit. Where on earth did you get that idea? The two flying prototypes were destroyed in landing accidents. Yes, the third unfinished prototype was captured by the US, but there were never any self-destructing plans.
Because many people don't like it when old threads are "bumped" to the top of the page with posts such as "when is it going to be done " or "I liek this" or even "pleze finish" even though the mod was often last worked on more than 6 months ago.
