I'm confused. The standard reason given it failed was the plans were leaked on purpose to the Soviets that had flaws to try (successfully) to make it crash. I'm happy it's an urban legend, but it was up there with the NN Tank story and the Gas Pipeline story (yet to be disappointed that this too is legend) as a common pre-WWW engineering story. Why no mention? Even to nix the legend or for old times sake.
