A 1959 Boeing concept for an airbreathing HTOL booster for Dyna Soar. Compared to the other pure-rocket VTO boosters, this would have been a monster… far bigger, far heavier, far, far more expensive. Which almost certainly explains why not only did such a booster not get serious study further down the line for Dyna Soar, it didn’t even rate detailed diagrams in the reports.
Staging would have been an interesting show.
NOTE: The isometric artwork for baseline concepts 4-7? Not available, sadly.
