From the Jay Miller archive, a 1964 cutaway illustration of the Boeing 733-197 supersonic transport. This was relatively low capacity compared to the later 2707 designs, being somewhat more like Concorde. I’ve seen and scanned several different versions of this, but each has been substantially flawed (this one is gray and the wingtips are out of focus… another is color, but was chopped in half to fit in a proposal, etc.). If anyone might happen to have a high-rez, clear color version, I’d love to see it.
