Exactly. Ask yourself, how long does this normally take to go from A to B? One day you've got top engineers with a contemporary concept, but the military says nah we've got to have something way better. So they really go to work on it until they can confidently deliver a 33-page futuristic well-engineered proposal with a prototype scale model and then the military says yes right away. What's normal here, weeks, months, even years? That's what's impressive in 48 hours, nobody could expect a complete set of blueprints, they had to first determine if prints would even be realistically possible. You know their slide rules were flying like few could do. With engineers like this why would you use anyone else?
