In aviation, those who dare to dream are either visionaries or insane. The long road of aviation history is filled with dead-end side roads of designs that simply boggle the mind. Those designs aren't just limited to fanciful thinking by eccentrics, either. Lockheed in the late 1960s devoted a surprising amount of effort to one of my favorite designs that most certainly falls into the "YGBSM" category ("You Gotta Be Sh*tting Me"- the unofficial motto of the USAF Wild Weasels, allegedly what was said by the pilots and WSOs who attended the first briefing on what was then a secret project). At the time Lockheed's Skunk Works had been looking at the feasibility of building an ultra-large transport for the US military and heading into the early 1970s the design evovled into the CL-1201 tailless aircraft that would have been for lack of a better description, a flying aircraft carrier.
