The 1959 Dyna Soar design from the Martin Company, designed by Hans Multhopp (formerly of Focke-Wulf). This was from when the Dyna Soar was a sub-orbital research vehicle meant to be lobbed by a modified Titan I ICBM. Note the inclusion of a turbojet engine for landing purposes, a common design element at this stage in the program.
Note that the cockpit of this little spaceplane was designed to be ejected in the event of an emergency. At this stage in the Dyna Soar program, the vehicle had lost its role as a bomber, and had been reduced to an R&D vehicle, thus the “cargo bay” stuffed full of equipment. Boeing’s final Dyna Soar design also had the instrument-filled cargo bay, but they fully expected to be able to ditch the instruments (which were mostly to measure and record pressure and temperature data all around the vehicle during re-entry) once the testing phase was over, and then proceed to fill the bay with useful payload, everything from anti-satellite hardware to passengers going to space stations.
The turbojet would very quickly be abandoned as weight climbed, meaning the Dyna Soar would glide to a landing much like the Space Shuttle.
A full-scale mockup of the cockpit was built… note that it appears to be made of cardboard. Cheesy, but perfectly adequate for preliminary layout purposes. Plus, some little kid may have gotten one hell of a spiffy Space Patrol Rocket to play in after its utility for Martin was finished. Note also the side-stick controller.
I wonder if you have better images of that cockpit. One with detailed markings of instrumentation? I suppose dimensions are out ouf the question? 😉
