> The first prototype of the B-52 may have been designed in a weekend. Not even that is true. Here's the timeline from the article. > In July of 1948, Boeing received a contract from the still-new U.S. Air Force to design and build a new heavy bomber. ... > So when Boeing’s three-man presentation team arrived at Wright Field Air Force Base on October 21, 1948 ... > Warden suggested to the Boeing team that they do away with their design and come back to him with a new one that included turbojet engines ... unbeknownst to Warden at the time, Schairer happened to be carrying some work he’d already done on the possibility of a jet-powered bomber in his briefcase, giving him just enough of a foundation to think a redesign might be possible ... >The next morning, which happened to be a Friday, the Boeing team returned with their newly jet-powered B-52 design, only to find that Warden remained unimpressed. ... > The two soon joined Schairer, Wells, Carlsen, and Blumenthal in the increasingly cramped hotel room, pouring over sketches and quickly-scribbled mathematical computations. Computers wouldn’t become a common facet of aviation design for decades to come. It was up to these six men and their witts to design an entirely new bomber… and they had just 48 hours to do it. .. > By Sunday, the team had compiled a full proposal that they turned over to a local stenographer to type up a clean copy. By Monday morning, they arrived back in Warden’s office with not only a fully-realized 33-page B-52 proposal but a silver, hand-crafted, 14-inch model of the bomber itself. Warden immediately took to the weekend design. So, July -> October 26th (Monday morning) 4 Months isn't bad at all but it's not quite the 4 days suggested in the headline.
